Which legislation required TikTok's parent company ByteDance to divest the app or face a U.S. ban by January 19, 2025?

The legislation in question is the Protecting Americans from Foreign Adversary Controlled Applications Act (PAFACA). This federal law, signed by President Biden on April 24, 2024, specifically targeted social networking services deemed a national security threat due to their control by foreign adversaries. The act explicitly applied to ByteDance Ltd. and its subsidiaries, including TikTok, requiring them to either divest the application or face a U.S. ban. The original deadline for ByteDance to become compliant was January 19, 2025.

The rationale behind PAFACA stems from bipartisan concerns among U.S. lawmakers regarding TikTok's Chinese ownership and the potential for the Chinese government to access sensitive American user data or influence public opinion through the platform's algorithms. Proponents of the legislation argued that applications controlled by foreign adversaries could be "weaponized" to target, manipulate, and surveil millions of Americans. This act followed earlier attempts to ban TikTok, which were often challenged on First Amendment grounds. PAFACA, however, was designed to address national security threats related to corporate control rather than regulating content, a distinction upheld by the Supreme Court in January 2025.

Despite the January 19, 2025 deadline, the enforcement of PAFACA experienced delays. On January 20, 2025, President Trump, following his inauguration, issued an executive order temporarily halting enforcement for 75 days. Subsequent executive orders further extended this deadline. Ultimately, in December 2025, TikTok reportedly agreed to a sale that would allow its U.S. operations to continue in compliance with the act's terms, with a plan for a newly established joint venture majority-owned and controlled by U.S. persons. This complex interplay of legislative action, legal challenges, and executive orders highlights the ongoing debate surrounding national security, data privacy, and the global reach of social media platforms.
