WATCH: Mary Trump says her uncle will use remaining time as POTUS “taking a wrecking ball to the United States government”

Appearing on “The View,” niece of President Trump, Mary Trump accused her uncle of “behaving like an immature bully” and said “it is impossible for Donald to believe that he lost.”

Mary told the co-hosts of The View “He’s lost before in his life. But, he’s never had to be in a situation in which he can’t somehow turn that loss into a win either through cheating or buying his way out of a jam, or using somebody else’s connections in power. There’s literally nothing he can do about this.”

“So, it’s sort of unfathomable because in my family, losing was literally the worst thing you could do. So it’s putting enormous amounts of pressure on him,” she added.

Predicting his next steps, Mary said ” he’s going to continue to undermine peoples’ faith in our government and our institutions. And again, it’s just another 48 days he has to keep, you know, taking a wrecking ball to the United States government.”

Joy Behar asked Mary “How is he hurting himself, in your mind?”

Mary responded “Well, he’s making himself look like a sore loser. He’s behaving like an immature bully who the only thing he has left right now is his grievance.”
