A bill that could ban TikTok has passed both chambers of Congress and now heads to President Joe Biden’s desk, where it will likely be signed into law.

The bill, if signed, would require TikTok’s Chinese parent company, ByteDance, to sell the app or it would be banned in the United States. TikTok has confirmed that if the bill becomes law, it will seek a federal lawsuit. Court challenges would likely hinge on national security and free speech concerns.
