My answer on this is the same as it was the last time that it was asked:
I could see DeSantis refusing to sign off on an extradition request because "something something politically-motivated prosecution," in which case, the state of New York would file a petition for a writ of mandamus in the Northern District of Florida to order DeSantis to proceed with the extradition of Trump. The District Court would presumably agree & issue a writ of mandamus to compel DeSantis to surrender Trump, & on appeal, the 11th Circuit would presumably affirm.
It might end up all coming down to a majority on SCOTUS - which hasn't been all that kind to Trump when it comes to his personal vulnerabilities (see: Trump v. Mazars) - having to decide whether to overrule its unanimous 1987 decision in Puerto Rico v. Branstad, in which they held that the governor of the asylum state has no discretion in performing their duty to extradite & that a federal court may enforce the governor's duty to return the fugitive to the demanding state. I don't see them doing so. At worst, it's a 6-3 decision (probably written by Roberts &) joined by all but Thomas, Alito, & Barrett.
In any event, extradition would only be the end of the beginning, because you know we'd end up getting an utter Trumpian sh*tshow involving as many floods of motions, petitions, hearings, & - ultimately - appeals in the NY courts (&, inevitably, the federal courts too).
Couldn't the Biden DOJ just hold him in contempt and then actually arrest him if he tries anything?
That's not how anything works. The DOJ would have literally nothing to do with this beyond filing an amicus brief in federal court supporting the case that NY would presumably file autonomously against FL on its own, with no other federal involvement yet because - again - there'd be no legal jurisdiction for them to even get involved at such a juncture.
I hope he protects Trump from unfair deep state prosecution, but I doubt it’ll get to that stage in the first place.
