Trump mocked for threatening to endorse opponents of Lisa Murkowski: 'You lost it, old man'

On Thursday, President Donald Trump attacked Sen. Lisa Murkowski (R-AK) as disloyal in the wake of her public criticism, emphasizing all the money he gave her state and saying he would back any candidate opposing her "good or bad."

Commenters on social media promptly deluged the president in mockery for his threat.
