“I watched some of the testimony, even though I'm in Europe, of Strzok. And I thought it was a disgrace to our country. I thought it was an absolute disgrace,” Trump told CBS News.

“Where he wants to do things against me before I was even, I guess before I was even the candidate. It was a disgrace. And then he lied about it," Trump added.

Strzok and former FBI lawyer Lisa Page, with whom he was having an affair, exchanged text messages critical of Trump during the 2016 campaign.

“He was a disgrace to the FBI,” Trump told CBS News. “So when I look at things like that and he led that investigation or whatever you call it. I would say that yeah, I think it hurts our relationship with Russia. I actually think it hurts our relationship with a lot of countries.”
