WATCH: Mary Trump warns what her uncle will do post-presidency will be “terrible” for the U.S.

Appearing with Chris Cuomo on CNN, President Trump’s niece Mary warned she does not think her uncle win run for President again, but what he will do will be “terrible” for the U.S.

Mary tells Cuomo she expects her uncle to  “take the position of spoiler because he lost so decisively,” claiming “he cannot bear the thought of losing.”

“He’s going to put considerable energy, as least as long as he’s able to, into delegitimizing Biden’s win and his administration,” she says while warning it will be “terrible” for the U.S.
