"unproved national security problem" and yet Congress was fairly well galvanized to vote for this bill after their intelligence briefings - multiple senators seem to want the briefing declassified: https://www.npr.org/2024/03/21/1239691465/tiktok-ban-bill-se...

Say what you want about the US government, Americans vote for them and their job is to synthesize the information brought to them and take action. The Senate obviously wasn't as overwhelmingly enthusiastic about this bill as the house, but it sure seems like people on capital hill saw something concerning.

We should all probably want this information to be declassified so we can judge it for ourselves, but until then it feels unjustified to say there is no basis for the national security concern
