Congress voted to force a sale or ban of TikTok because a bipartisan majority concluded that Chinese ownership of the app is itself a national security threat. Lawmakers focused on three linked risks: that Beijing could compel ByteDance to hand over data on roughly 170 million American users, that it could quietly tune TikTok’s recommendation algorithm to push propaganda or bury unwelcome topics, and that no technical safeguard short of separating TikTok from its Chinese parent could neutralize either risk. That reasoning produced the Protecting Americans from Foreign Adversary Controlled Applications Act, signed in April 2024, which gave ByteDance a deadline to divest TikTok’s U.S. operations or see the app pulled from American app stores.
Chinese Law Makes Ownership the Problem
The central legal concern is not what TikTok has done but what its parent can be ordered to do. China’s 2017 National Intelligence Law says that “any organization or citizen shall support, assist, and cooperate with state intelligence work according to law.”1Lawfare. Beijing’s New National Intelligence Law: From Defense to Offense That statute sits alongside China’s 2017 Cybersecurity Law, the 2021 Data Security Law, and an updated Counter-Espionage Law, all of which expand the government’s authority to demand access to data held by Chinese companies.2Office of the Director of National Intelligence. NCSC Bulletin on PRC Laws Permitting Data Access
TikTok collects a lot to hand over: phone numbers, precise location data, device identifiers, browsing habits, private messages, and social connections. FBI Director Christopher Wray summarized the concern in congressional testimony: “This is a tool that is ultimately within the control of the Chinese government.”3The New York Times.

The Incidents That Made the Risk Concrete
Two disclosures moved the debate from theory to evidence. In 2022, BuzzFeed News reported on leaked audio from more than 80 internal TikTok meetings in which employees acknowledged that China-based ByteDance engineers had repeatedly accessed nonpublic U.S. user data. One Trust and Safety employee said, “Everything is seen in China.” Another described a Beijing-based engineer as a “Master Admin” with “access to everything.”4BuzzFeed News.

Then in December 2022, ByteDance’s own internal investigation confirmed that employees in its Internal Audit department had accessed the TikTok data of American journalists at Forbes, BuzzFeed, and the Financial Times to track their physical locations and try to identify company employees suspected of leaking to them. ByteDance fired four employees and its chief internal auditor, Chris Lepitak. CEO Rubo Liang said the surveillance “significantly undermined” public trust.6The New York Times.

Algorithm Manipulation and Propaganda
The second half of the case involves what Americans see on the app, not what leaves it. Casey Blackburn, an assistant director of national intelligence, stated in a court affidavit that the Chinese government could coerce ByteDance “to covertly manipulate the information received by the millions of Americans that use the TikTok application every day, through censorship or manipulation of TikTok’s algorithm.”8NBC News. TikTok Says It’s Not Spreading Chinese Propaganda, but the US Says the Risk Is Real
Researchers pointed to skewed content patterns. Studies by the Network Contagion Research Institute at Rutgers University, cited in congressional testimony and court filings, found that topics sensitive to the Chinese government — Tiananmen Square, Uyghur repression, Hong Kong protests, and Tibetan independence — were significantly underrepresented on TikTok compared with other platforms. A 2024 follow-up concluded that TikTok’s algorithm “actively suppresses content critical of the Chinese Communist Party while simultaneously boosting pro-China propaganda.”8NBC News. TikTok Says It’s Not Spreading Chinese Propaganda, but the US Says the Risk Is Real A New York Times analysis comparing TikTok and Instagram found that content about Hong Kong protests appeared on TikTok at just 0.6% of the rate it appeared on Instagram, and content about Tiananmen Square at only 1%.3The New York Times. TikTok Ban Bill: What to Know
The Justice Department was candid about the limits of its proof. It acknowledged in court that it had “no direct evidence” China had already used TikTok for propaganda inside the United States, but argued that the risk was significant given China’s legal framework and political structure.8NBC News. TikTok Says It’s Not Spreading Chinese Propaganda, but the US Says the Risk Is Real Congress accepted that framing: the point of the law was to remove the capability, not to punish a documented act.
Why a Technical Fix Wasn’t Enough
TikTok spent roughly $1.5 billion on a program called Project Texas, which was meant to route all U.S. user data to Oracle-managed servers and wall it off from ByteDance in China. The Committee on Foreign Investment in the United States, which had been reviewing ByteDance’s ownership since 2019, concluded the plan was inadequate. ByteDance kept control over the software and source code behind TikTok, the team overseeing secure U.S. data reported to ByteDance leadership in China, and Wall Street Journal reporting found that U.S. data was “still sometimes shared” with the parent company despite the safeguards.9The Wall Street Journal. TikTok Pledged to Protect US Data. It’s Still Struggling
On Capitol Hill, key lawmakers dismissed Project Texas as a “marketing scheme,” in Representative Cathy McMorris Rodgers’s phrase, and Representative Jay Obernolte argued that TikTok’s stated technical goals were “not technically possible.” The House concluded that “no remedy is possible, aside from a sale or a ban.”10Lawfare. What Happened to TikTok’s Project Texas CFIUS reached the same conclusion, finding that technical and behavioral mitigation could not overcome the structural risk of Chinese ownership under Chinese law.11Congressional Research Service. TikTok: Frequently Asked Questions and Issues for Congress That is the conclusion the legislation encodes.
What the Law Actually Does
Representative Mike Gallagher, a Wisconsin Republican who chaired the House Select Committee on China, and Representative Raja Krishnamoorthi, an Illinois Democrat, introduced the Protecting Americans from Foreign Adversary Controlled Applications Act on March 5, 2024. Cosponsors ranged from Nancy Pelosi to Dan Crenshaw.12House Select Committee on China. Gallagher, Bipartisan Coalition Introduce Legislation to Protect Americans

The statute makes it illegal for app stores and internet hosting services to distribute or maintain any application designated as controlled by a foreign adversary, and it names TikTok and ByteDance explicitly. It also builds in an escape hatch: the prohibitions lift if the platform completes a “qualified divestiture” that eliminates foreign-adversary control and precludes any operational relationship between the U.S. entity and the foreign parent. Enforcement runs through the Attorney General and the Justice Department’s National Security Division.16U.S. Department of Justice. Foreign Adversary Controlled Applications The law targets ownership, not the app; that framing is how Congress squared its national security case with a platform used by 170 million Americans.
Where the Case Now Stands
TikTok challenged the law on First Amendment grounds. The Supreme Court unanimously upheld it in TikTok Inc. v. Garland on January 17, 2025, applying intermediate scrutiny and finding the law content-neutral and justified by the government’s interest in preventing a foreign adversary from collecting sensitive data on millions of Americans. The justices emphasized that the statute imposed a “conditional ban” avoidable through a qualified divestiture, making it “not substantially broader than necessary” to address the threat, and deferred substantially to Congress’s national security findings.17Supreme Court of the United States. TikTok Inc. v. Garland, Nos. 24-656 and 24-65718The New York Times. Supreme Court Upholds TikTok Ban Law
The law took effect on January 19, 2025, and TikTok briefly went dark for U.S. users. President Trump then issued an executive order directing the Justice Department not to enforce it while a sale was negotiated, with further delays through 2025.19The White House.

The resulting entity, TikTok USDS Joint Venture LLC, has majority American ownership and a majority-American board, with Oracle, Silver Lake, and the Emirati investment firm MGX each holding 15%. ByteDance retains 19.9%. TikTok’s algorithm has been licensed to the joint venture and is being retrained on U.S. user data inside Oracle’s cloud, with Oracle auditing source code and monitoring compliance.22BBC. TikTok US Deal Closes Whether that arrangement actually satisfies the law’s ban on any “operational relationship” with ByteDance is contested. Senator Ron Wyden said the deal would not do “a thing to protect the privacy of American users” and added, “It’s unclear that it will even put TikTok’s algorithm in safer hands.”23BBC. TikTok Deal Scrutiny The underlying reasons Congress acted — Chinese legal authority to compel data access, evidence that access had already happened, algorithmic influence that no technical fix could reliably contain — have not changed.
