Is the new push to ban TikTok for real?

The House passed an audacious bill on Wednesday that could potentially ban the social media app TikTok, generating a furor on Capitol Hill and online.

President Joe Biden has said he will sign the bill if passed. But it also still needs to clear the Senate, where discussions are underway to draft companion legislation.

Sen. Mark Warner (D-VA) will be at the center of the charge in the Senate and has been coordinating with the bill’s House sponsors as well as his Republican counterpart on the Senate Intelligence Committee, Sen. Marco Rubio (R-FL), a Senate aide familiar with the discussions told Vox.
