I think she is the one who wants out. She’s tired of leading him around like a stray calf...as if no one notices. He’s an embarrassment to her.
He is so far gone he is incapable of answering media questions. Just now he shuffled out of the "statement" he gave trying to read the teleprompter as to why the horrible border bill and Ukraine/Israel funding bill should pass. Literally incapable of answering questions on something supposedly important to him. So instead, he says the border crisis is because of Trump. Does his handlers believe people are that stupid?
