Donald Trump attended a press conference with Japanese Prime Minister Shinzo Abe on Monday night in Tokyo, and doubled down on his support for North Korean dictator Kim Jong Un, especially his comment that Joe Biden is a “low IQ individual”.

Last week, North Korean state media called Biden an “imbecile.”

During the press conference in Tokyo Monday, Trump claimed that Biden is a “low IQ individual,” adding that Kim is “probably right about that.”

“Kim Jong Un made a statement that Joe Biden is a low IQ individual. He probably is, based on his record. I think I agree with him on that,” Trump said.

When he was asked a follow-up question, Trump railed on the Obama administration’s foreign policy with regards to North Korea and Iran, singling out the Iran nuclear deal as a disaster.

“I don’t take sides as to who I’m in favor of, who I’m not,” Trump added. “But I can tell you that Joe Biden was a disaster. His administration with President Obama, they were basically a disaster when it came to so many things.”

Trump had drawn criticism on Sunday for a tweet he’d sent that said he smiled with Kim described Biden as a low IQ individual.

In the past, it was unusual for a U.S. president to criticize a political rival while overseas, though Trump has moved away from that precedent.

Trump is the first U.S. president to engage in direct talks with a North Korean leader, and Trump showered Kim with praise during his remarks, calling him a very smart man.

Biden is running for president and leads polls in the Democratic primary. He has put his electability at the center of his campaign while arguing he is the Democrat best positioned to defeat Trump in an election next year.
