There is no mechanism by which he can do that.
He can't abolish the 14th amendment: he tried anyway.
He can't summarily fire hundreds of thousands of long standing, good standing, government employees without cause: he tried and mostly succeeded.
He can't rename international geography: he tried anyway.
He can't start slapping tariffs on partner nations: he tried anyway and is still threatening to do it.
He can't randomly appoint an unelected individual to start slashing budgets and departments: he did it.
He can't summarily end emergency aid to the states: he has.
He can't abjectly stop funding, or reclaim already dispersed money: he has.
Trump is a criminal: he doesn't need a mechanism, he just needs to get away with it.
