Quick recap: In April of last year, the US Senate passed a bill stating that TikTok would be banned across the country due to national security concerns — unless the Chinese company ByteDance sold its stake in the app. Current US President Joe Biden swiftly signed it into law the day after.

The president-elect Sunday pledged an executive order, hours into his second term, returning access for American users, at least temporarily.

TikTok thanks Trump for giving companies that carry the platform enough “clarity and assurance” to restore U.S. access, the latest dizzying development in the battle over the app.
