“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 told reporters Monday during a joint news conference with Japan's Prime Minister Shinzo Abe.
The comment came after Trump had already tweeted his approval of Pyongyang's mockery of his potential 2020 election opponent and downplayed a recent short-range missile test by North Korea.
On his CNN show Monday night, Cooper delivered a commentary in which he criticized Trump for "choosing to believe a nuclear-armed adversary over his own handpicked national security adviser."
Cooper was referring to John Bolton, who said there is “no doubt” that recent short-range missile launches by North Korea are in violation of U.N. Security Council resolutions.
"Compounding it all, the president also tried to enlist this dictator into what exactly? Denouncing a political rival?" Cooper said, highlighting a clip in which Trump said "who knows" and "it doesn't matter" when asked about why North Korea conducted the recent missile tests.
"The president of the United States should know, and that does matter,” Cooper said.
“And if the president doesn’t know, he should take his fingers off the Twitter machine and maybe pick up a briefing book and do something that we all know he rarely does, which is read. The president still acts like he’s a powerless real estate developer in New York, lying about building height and who he’s dating and calling up gossip columnists using pretend names to crow about his sexual prowess. The president is acting like a bystander to everything that's going on."
Cooper went on to claim that Kim Jong Un "seems to have managed to tap into" Trump's need for "adulation."
"It is plain to see President Trump telling us all that whatever it may mean to the country he was elected to govern, he measures success by the number of people showering him with adulation. At times, 10,000 screaming fans, or sometimes maybe just one fat little dictator with blood on his hands and missiles in his arsenal," Cooper concluded.
