Trump has already told everyone what he will do: pardon all the Jan 6 rioters, and seek REVENGE.
Revenge against everyone that has pointed out that Trump is an incompetent wannabe dictator, against most of the people he appointed to his own government, nearly all of whom now hate his guts.
He will seek to reward above all, himself, going on million dollar golf junkets where the Secret Service mus pay admission to his various golf clubs.
He will turn the White House into a poorly run circus again.
Immigration problems are the result of Congress refusing to pass legislation. The Republicans have refused all attempts to change immigration law, and will continue to do so.
