“He better be careful what he’s wishing for. That’s a disgusting statement for him to make. For him to make a statement like that is a very dangerous statement,” Trump said during a wide-ranging interview on Fox & Friends.

On Wednesday, video surfaced of Holder's comments, which he made while campaigning for Georgia gubernatorial candidate Stacey Abrams (D).

Holder, who served under former President Obama, said that the "new Democratic Party" needed to "fight" for its ideals.

"Michelle [Obama] always says that, you know, ‘When they go low, we go high.’ No. When they go low, we kick them." Holder, who served under former President Obama, said "That’s what this new Democratic Party is about," Holder said. “We’re proud as hell to be Democrats. We’re going to fight for the ideals of the Democratic Party."

Holder, who has said he is interested in a possible 2020 White House bid, later clarified in the speech that when he says to "kick them," he doesn't mean doing anything inappropriate or illegal.

Trump on Thursday also targeted Holder as a possible Democratic opponent in 2020, saying "he's got some problems" and predicting that the Democratic primaries "would gobble him up."

"I don’t see him running," Trump said. "And if he did run, I think he gets gobbled up before he ever gets to the election itself. I think the primaries would gobble him up.”

"So far, I like every one of them," he said.

"I just hope they stay healthy. And I hope they fight it out. Any one of them I’d like. I just hope that we don’t get any star or good thinker,” the president added about the possible Democratic Primary field.
