I don't know the legal intricacies of this situation. I believe it is unprecedented and new legal arguments and theories will appear.
U.S. Grant was arrested for repeat offenses of speeding in his horse and buggy in DC but was not jailed. He had to walk back to the WH.

I do not like to think of Trump in a NYC jail without security including a food taster.
So what's the plan?
They would have to go to Florida!
There are set procedures.
Extradition Between States: Defenses There aren't many defenses to extradition. As long as the process and procedure found in the U.S. Constitution and federal law have been followed, the fugitive must be surrendered to the demanding state. However, there are a few defenses that have been identified by the Supreme Court, such as:
whether the extradition request documents are in order; whether the person has been charged with a crime in the demanding state; whether the person named in the extradition request is the person charged with the crime; and whether the petitioner is, in fact, a fugitive from the requesting state. If the fugitive's petition or writ for habeas corpus is unsuccessful, the arresting state must hold them for the demanding state. The demanding state then has 30 days to retrieve the fugitive. If they don't, the arresting state may release them.
