(CNSNews.com) -- While meeting with Canada's prime minister at the NATO summit in London today, President Donald Trump criticized House Intelligence Committee Chairman Adam Schiff (D-Calif.), describing him as a "maniac" and a "deranged human being."
Schiff, a liberal Democrat, is leading the impeachment effort in the House against President Trump.
At the summit, a reporter asked Trump, "What do you want to learn from Adam Schiff's testimony" should he testify in the impeachment inquiry?
Trump said, "I learn nothing from Adam Schiff, I think he's a maniac. I think Adam Schiff is a deranged human being. I think he grew up with a complex for lots of reasons that are obvious."
"I think he's a very sick man," said the president. "And he lies. Adam Schiff made up my conversation with the president of Ukraine. Now, one of the reasons people keep talking about it is because that is what they saw."
"We have a perfectly beautiful three- or four-page transcription and in the other case a two-page transcription of the conversation," he said.
"This guy is sick," said Trump. "He made up the conversation. He lied. If he didn't do that in the halls of Congress, he'd be thrown in a jail. But he did it in the halls of Congress and he's given immunity."
"This is a sick person, he's a liar," said Trump. "And, by the way, Nancy Pelosi knew he was lying and she went on a show [ABC] with George Stephanopoulos, and she said he told the truth. so she was lying too."
"These people are deranged," said Trump.
