Trump was just asked about the impeachment hearing during his press conference with the Turkish leader.

He took the first question from the pro-Trump One America News Network.

"You're talking about the witch hunt, is that what you mean?" the president said. "I hear it's a joke."

Noting that he did not have time to watch the hearing, he said: "This is a sham, it shouldn’t be allowed."

He again maintains his call with Zelensky was "perfect".

"I'm gonna find out who's the whistleblower, because the whistleblower gave a lot of very incorrect information about my call," Trump said.

The president added that he will be releasing a second call, presumably with Zelensky, "which actually was the first of the two" on Thursday.

Trump said he's heard the congressional evidence was just "all third-hand information, nothing direct at all. Can't be direct, because I never said it."
