Charles Krauthammer characterized Donald Trump Jr.'s defense for meeting with a Russian lawyer as "incompetence," saying it's not a good justification.

Krauthammer said Trump Jr's explanation for why the meeting was not suspicious collusion was that "it didn't work out."

Trump Jr. said Natalia Veselnitskaya promised to have what amounted to opposition research on Hillary Clinton in Spring 2016.

He called the meeting a "waste of 20 minutes" and not particularly memorable.

Krauthammer said he's defended Trump Jr. and his father against accusations of collusion because there "wasn't [any] 'there' there."

"[But] the denial of collusion is very weak right now because it looks as if Don Junior was receptive to receiving this information," Krauthammer said.

"It's a hell of a defense to say your collusion wasn't competent and it didn't work out," he said.

Trump, Jr. talks exclusively with Sean Hannity tonight at 10 PM ET on Fox News Channel.
