Biden and Congress want to ban TikTok. At this point it may be impossible.

Some insiders are even starting to worry that the government may never be able to meaningfully restrict TikToks use and are considering alternative approaches to mitigate any threat it poses.

I dont really care what Congress writes, or what the administration writes. Theyre not going to ban TikTok, said James Lewis, director of the Strategic Technologies Program at the Center for Strategic and International Studies think tank. They can ban financial transactions, or they can try to force divestiture. But they dont have the ability to ban TikTok itself.

The challenges that confront Washington as it works to rein in TikTok compound on each other. Between the companys steep price tag, antitrust concerns and expected resistance from Beijing, almost no experts believe Washington will be able to force ByteDance, TikToks Chinese owner, to sell the app. If divestiture fails, the government will need new authorities from Congress to prevent getting laughed out of court when it attempts a direct ban and theres no guarantee lawmakers can get on the same page to grant those powers in time for Biden to use them.

Even if Capitol Hill can deliver on a new law, a legal battle over the impact of a TikTok ban on the First Amendment is almost inevitable. All roads lead to court, said Lewis. ByteDance has tons of money, theyll hire an army of lawyers. And this will be fought out. He and others expect the government would likely lose any First Amendment case.

Optimistic TikTok hawks compare their efforts with Washingtons successful ban on networking equipment made by Huawei, the Chinese telecommunications giant suspected of serving as Beijings sock puppet. But there are meaningful differences: While the ban on Huawei hardware impacted the bottom line of a few U.S. telecom firms, it had virtually no bearing on the free speech rights of millions of Americans. And Washington seemed to have more evidence that Huawei posed a security threat, including the discovery of major security flaws in its systems. A similar smoking gun does not appear to exist for TikTok.

As Washington stares down the dizzying obstacle course, theres an increasing sense that its already missed its best chance to ban TikTok. Time is not on our side, said Rep. Mike Gallagher (R-Wis.), chair of the new House Select Committee on China. Every day that passes is a day that we have not taken action on this critical issue. And I think TikTok is trying to wait out the clock.

TikTok spokespeople declined requests to comment on the social media giants predicament, discuss its strategy or handicap its chances in a court battle with Washington.

But banning a popular communications tool, foreign or otherwise, is virtually without precedent in the United States. Washington has tried this once before and failed: In August 2020, former President Donald Trump attempted to ban TikTok and several other Chinese-owned apps by executive order. A federal court threw out that effort within months.

Though Bidens attempt is more deliberate, starting with his support for a bill in Congress that would give him new authority to restrict foreign apps, any fresh effort to ban TikTok is likely to hit a similarly daunting set of hurdles.

With an estimated 150 million monthly American users, talk of a TikTok ban has prompted fear of a political backlash. The social media giant has also hired plenty of lobbyists since its tussle with the Trump administration, making it an even tougher nut for Washington to crack.

But in this case, the politics may almost be a sideshow. The real story, say those who have looked ahead to the practical steps of a ban, is the U.S. governments constitutional inability to shut out any digital platform that hasnt already proven a clear threat.

A repeat of Trumps mistakes

Years after Trumps failure, the Biden administration is attempting a more methodical approach to a TikTok ban. But it may already be steering into one of the former administrations errors.

Trumps first mistake, according to former administration official Keith Krach, was his attempt to force the sale of TikTok to Microsoft, Oracle or another U.S. tech company. Krach called the effort a major distraction that gave ByteDance the breathing space needed to challenge Trumps executive order.

It was a strategy that wasnt going to work. And yeah, that took up quite a bit of time, said Krach, who served as Trumps undersecretary of the State Department in charge of economic growth, energy and the environment.

Now Washington is back to where it was in 2020. In March, reports emerged that the White House acting through the interagency Committee on Foreign Investment in the U.S. is now demanding that ByteDance sell TikTok to a company it can trust, or face a full-scale ban.

But three years after Trump tried to force a sale, the environment for such a deal is even worse. TikTok is bigger, more popular and more valuable and Washington is far more aggressive about blocking big mergers. Virtually no one expects a buyer to materialize.

While ByteDance keeps TikToks valuation private, most observers believe the app is worth well over $40 billion. That likely puts it out of reach for all but the richest companies or investors. And at least one possible buyer has already spent that amount on a separate social media platform. (Wheres Elon Musk when you need him? asked Lewis.)

Tech giants like Meta or Google have seen their own valuations fall from their 2021 peaks, making it tougher for those companies to scrape together the cash to buy TikTok. And even if they could find the money, antitrust concerns would likely cause them to steer clear of the Chinese-owned app.

Antitrust concerns likely take both Meta and Google (which owns YouTube) out of the running as potential TikTok buyers, said Daniel Francis, a former deputy director of the FTCs Bureau of Competition whos now a law professor at NYU. Any large tech deal will get close antitrust scrutiny in the present climate, he said.

Companies like Amazon or Microsoft, which control smaller shares of the social media market, may be better positioned to buy TikTok without triggering a competition complaint. But theyre just as unlikely to pick up a property laden with so much baggage.

All of these companies are skittish, said Florian Ederer, an economics professor at Yale University who specializes in antitrust policy. They already have plenty of antitrust problems. They dont want any additional ones.

Given a lack of obvious buyers, Ederer said the most realistic scenario could be an initial public offering, which would spin off TikTok into an independent (and presumably U.S.-based) entity. But IPOs are notoriously complicated, and also tightly regulated and Ederer said theres still no guarantee that a domestic spin-off would satisfy Washingtons security concerns.

Youre essentially just making [TikTok] separate, Ederer said. What prevents them from sharing information or sharing data with their previous Chinese parent?

The looming China veto

Even if those hurdles are cleared, the Chinese government is expected to sabotage any attempt to change TikToks ownership.

ByteDance is one of Chinas most globally successful tech companies, and TikTok runs on powerful and closely guarded software systems. In response to the Trump administrations abortive ban, in 2020 Beijing updated its export control rules so that Chinese-owned algorithms including those that power TikToks personalized recommendation engine could be blocked from leaving the country.

Lindsay Gorman, a former technology and national security adviser in the Biden administration who studies emerging tech at the German Marshall Funds Alliance for Securing Democracy, said Beijing is likely still mulling whether it should block Washingtons effort to force a TikTok sale. But she said some pushback is a virtual certainty.

Chinas definitely unlikely to let the U.S. policy process play out how its going to play out, and sit on the sidelines, Gorman said.

The Biden administration knows how badly the odds are stacked against a TikTok divestiture. I dont see how they can make the sale work, said one person familiar with the national security discussion inside the administration, who requested anonymity in order to address sensitive talks.

From the price tag to antitrust concerns and the expectation that Beijing will withhold TikToks algorithm, the person claimed the prospect of a TikTok sale is almost a false premise.

I think Treasury was optimistic that Meta or Amazon would just show up and save the day, the person said. We started to go down this path, and it became clear to them that this was much more complicated.

Can Congress pick up the ball?

If divestiture fails, the Biden administration has indicated it will seek to impose a direct ban on TikTok. But it would first need a big assist from Capitol Hill.

When federal judges blocked the Trump administrations TikTok ban in 2020, they did so in part based on violations of the Berman amendments obscure but important 30-year-old provisions in the International Emergency Economic Powers Act that allow for the free flow of informational material from adversarial nations.

The White House has suggested it needs Congress to blow a hole in the Berman amendments before it can target TikTok on firm legal footing. And last month it backed the RESTRICT Act, a bipartisan bill from Senate Intelligence Chair Mark Warner (D-Va.) and Senate Minority Whip John Thune that would short-circuit the Berman amendments and formally allow the administration to ban technologies from China and five other countries.

But the RESTRICT Act is just one of several TikTok bills now percolating on Capitol Hill. That includes legislation from House Foreign Affairs Chair Michael McCaul (R-Texas), which advanced out of that committee last month on a party-line vote, as well as a bill backed by Sen. Marco Rubio (R-Fla.) and Reps. Gallagher and Raja Krishnamoorthi (D-Ill.). More bills may be coming late last month, House Energy and Commerce Chair Cathy McMorris Rodgers (R-Wash.) said shes working on her own TikTok bill.

All of these lawmakers back a federal ban on TikTok, and most of their bills aim to undercut the Berman amendments to achieve that goal. But their supporters are already sniping at one another over the details. While key House Republicans argue that the RESTRICT Act gives too much leeway to TikTok, some GOP senators claim the bill goes too far and could restrict civil liberties. Meanwhile, House Democrats wary of angering young voters and stoking anti-Chinese sentiment are distancing themselves from Warner and other Senate Democrats pushing a hard line on TikTok.

The mishmash of bills and splintering of viewpoints suggests a long and testy process will need to play out in Congress before the administration can move on a TikTok ban. And given the alleged national security concerns raised by the app, Washington doesnt have time to spare.

We should all act with a greater sense of urgency, said Gallagher. The representative said he plans to sit down soon with McCaul, McMorris Rodgers and House leadership to figure out whats the most sensible path forward.

Warner said the RESTRICT Act is still moving forward, and that he and Thune are now engaged in sausage-making with their House counterparts. But even legislative pushes with broad bipartisan support regularly get bogged down on Capitol Hill. Krach compared the congressional TikTok debate to early talks around last cycles sprawling CHIPS and Science Act, which went through well over a year of discussion (and more than one near-death experience) before finally being signed into law last summer. That went through a lot of maturation, [and] I think youre gonna see the same thing, he said.

The Biden administration will be stuck spinning its wheels on a TikTok ban until Congress passes a fix to the Berman amendments. But even if lawmakers decide to beef up the presidents authorities, a more fundamental challenge awaits.

The First Amendment wall

A ban on TikTok from a newly-empowered White House would almost certainly trigger a legal challenge on free speech grounds. And while judges never seriously grappled with the First Amendment implications of a TikTok ban in 2020, even some China hawks believe the Constitution would block Washington if it tried again.

The ban stuff thats just politics, said Lewis. You cannot ban the First Amendment.

Proponents of a TikTok ban claim the national security risks posed by the app are self-evident. ByteDance is headquartered in China, and Chinese law requires companies to cooperate with any and all requests from Beijings security and intelligence services. Even if theres no evidence of nefarious activity, they claim its only a matter of time before the Chinese government flips a switch and weaponizes TikTok.

But that line of reasoning is unlikely to sit well with federal judges, who will be weighing the potential security risks with the imposition of real-world restrictions on the rights of 150 million Americans to post and exercise free speech on an extremely popular platform. (TikTok also has its own First Amendment rights, though its less clear how judges would rule if the company sought to assert them in court in response to a ban.)

Caitlin Vogus, deputy director of the Free Expression Project at the Center for Democracy and Technology think tank, said its theoretically possible that the government could convince a judge that the risk posed by TikTok is so high that a ban is the only option. But Washington would need to come armed with concrete evidence that the app represents a threat and so far, theres little to indicate such evidence exists.

Warner, when asked if hes seen classified material that indicates the TikTok threat is worse than the public record suggests, did not offer specifics: Some of this is still potential, he said.

Vogus said potential threats likely wont cut it in a courtroom. The government would be facing an extraordinarily high burden that it would have to meet before it could justify an outright ban, she said.

The First Amendment has trumped external threats before: Vogus and others pointed to the Supreme Courts 1965 ruling in Lamont v. Postmaster General, which dealt with the legality of restrictions on the mailing of foreign communist propaganda. Even at the height of the Cold War, the Court unanimously ruled that those restrictions violated the First Amendment and allowed the propaganda to continue.

Vogus laid out a few ways that courts could approach the First Amendment concerns raised by a TikTok ban. If judges decide that a TikTok ban represents a prior restraint on the speech of its users, she said Washington would have to prove an exceptional government interest in order to justify a ban. If they determine that a ban is based on viewpoints espoused by TikTok a real possibility, given the governments fears that Beijing will use the app to conduct covert influence campaigns the administration would need to prove a compelling government interest. Even if judges rule that a TikTok ban is neutral when it comes to content and viewpoint, the government would still have to prove that the remedy is narrowly tailored to serve a significant government interest.

Proponents of a TikTok ban, so far, have avoided discussing the free speech implications of the policy. When asked directly if he believed a ban could survive a First Amendment challenge, Warner would not comment on the record. A subsequent email with follow-up questions for the senators legal team on whether a ban would pass constitutional muster went unanswered by a Warner spokesperson.

After some prodding, Thune admitted there are First Amendment issues with a TikTok ban. And while the senator remains hopeful that his bill would allow an outright ban to withstand legal scrutiny, he said its possible that Washington will instead be stuck mitigating [TikTok] in some fashion.

Back at square one?

The array of obstacles now confronting the government on TikTok has led to the sense that Washington has already botched its best chances to rein in the Chinese-owned app.

The missed opportunity was last December, said Lewis. That was when CFIUS and ByteDance reached a tentative deal, known as Project Texas, which would theoretically have siloed off U.S. user data from Beijings surveillance. It was ultimately derailed by objections from the FBI and Department of Justice.

We might find ourselves going down the path of going to court, losing and then thinking about what a Project Texas would look like, said Lewis.

If TikTok is still alive and well and on peoples phones in two years, Washington may be looking for other ways to hit TikTok where it hurts. While the First Amendment likely limits the governments ability to ban the app outright, it could still target TikToks ability to conduct U.S.-based financial transactions. That includes potential restrictions on its relationship with Apple and Googles mobile app stores, which would severely hamper TikToks growth.

If your goal is to keep Chinese content from reaching American citizens, theres no way to do that, said Lewis. But if your goal is to keep Chinese companies from profiting from that content, we can do that.

With no end in sight to the escalating confrontation between the U.S. and China, it increasingly feels like TikTok is just a proxy in the larger fight between the worlds superpower and its near-peer challenger. And with no easy fix for the TikTok problem, the issue is likely to languish until the two nations reach a broader understanding.

The real problem is Chinese espionage, said Lewis. If we can find a way to mitigate that risk, you can move forward with TikTok. Otherwise, its just going to be messy.
