TikTok Shutdown, Ceasefire Begin as Trump Prepares to Take Office

This Sunday on "Face the Nation," host Margaret Brennan leads a critical discussion on a day of major global shifts. The program airs on the eve of Donald Trump's presidential inauguration. Two immediate changes dominate the agenda: a new ceasefire deal takes effect in a conflict zone, and the popular video app TikTok is officially shut down in the United States. To analyze these events, Brennan is joined by two key officials. Brett McGurk, the Biden administration's Middle East envoy, will discuss the fragile ceasefire. Incoming National Security Adviser Mike Waltz will also appear. He is expected to address the TikTok shutdown and the broader national security landscape for the new Trump administration.
