Rep. Hakeem Jeffries (D-N.Y.), the House Democratic Caucus chairman, has publicly slammed President Trump, calling him the "fake leader of the free world." 

The blasting comes after Trump agreed with criticisms of former Vice President Joe Biden made by the North Korean regime.

"North Korea fired off some small weapons, which disturbed some of my people, and others, but not me. I have confidence that Chairman Kim will keep his promise to me, & also smiled when he called Swampman Joe Biden a low IQ individual, & worse. Perhaps that's sending me a signal?" Trump tweeted on Saturday.

Jeffries then hopped onto his social media page to call out the president for siding with Korea.

"Many House Republicans wrap themselves in the flag and patriotic rhetoric," Jeffries tweeted. "But they have nothing to say when fake leader of the free world blatantly sides with a Communist North Korean Dictator? PHONIES."

Over the weekend, Jeffries had some more words for the president during an appearance on 'Meet The Press.'

"Donald Trump is functionally a studio gangster," Jeffries said. "He pretends to be a tough guy, but he is really just playing that role on TV. Hopefully, he will have gotten this temper tantrum out of his system. He can come back from Japan. We have crumbling bridges, roads, tunnels, airports, mass transportation systems. We need to get to work to fix it. We have a plan, and we'd like to do it in a bipartisan way."

He continued:

"We don't work for Donald Trump," he said. "We work for the American people. We have a constitutional responsibility to serve as a check and balance on a potentially out-of-control executive branch. But we will not overreach. We will not overinvestigate. We will not overpoliticize that responsibility. We will proceed as Speaker Pelosi has laid out, methodically yet aggressively to get to the truth.

"The only way to proceed is to make sure that politics don't dictate a decision to impeach or politics don't dictate a decision not to impeach," Jeffries added. "We need to follow the facts. We need to apply the law. We need to make sure that the Constitution is the guiding principle in terms of the way forward. "
