> So why should Biden stop it if he agrees with it?
That is my point. The Democrats made themselves look very bad with this situation and Biden did nothing and supported the bill anyway and just signed it.
In fact he replaced Trump's original EO with a worse one which includes still supporting the TikTok ban and Biden signed that last year which made it so that if the Democrats won the election, then TikTok would have been still completely banned with no reversal whatsoever.
In effect, those who voted for Biden or Harris also were voting for a TikTok ban, which that is beyond hilarious as everyone saw that he didn't halt the ban.
