Representative Cheney, 56, lost her Republican primary to Trump-supported challenger Harriet Hageman on Tuesday in Wyoming - yet hinted at a future presidential run.
The former president's son was the first to jump online to poke fun at her loss, writing: "Liz Cheney compared herself to Lincoln…LMFAO. That CNN & MSDNC fluffing got to her carpetbagger/warmonger head."
He further posted a clip of a man with his father's head on it dancing, writing: "Bye, bye, @Liz_Cheney. On the bright side, you won't have to pretend to be from Wyoming anymore."
