He's making tens of millions of Americans (especially including those who may not have otherwise been political) quite fond of him, bringing back a platform that has definitely been a net positive for him overall, undoing one of his predecessors 'achievements', and so on.
He came out against a ban on TikTok long ago (after initially being in support) and made it clear he'd work to reverse it the second the ban bill started gaining momentum.
So he can make a call and cancel a border security bill, but can't make the same call to cancel the TikTok portion of the spending bill before it passed?
Is it possible that TikTok solved their problem by purchasing $6 billion worth of Trump’s meme coin?
