"When I ran against them [Democrats] they were looking for dirt on me every day. That's what you do. Maybe you shouldn't, but you do. Nothing illegal about that," Giuliani told Fox News's Laura Ingraham on Wednesday night.

"Even if it comes from a Russian, a German, an American, doesn't matter," he continued.

Giuliani told Ingraham that there was no collusion between the Trump campaign and Russia because the campaign never used the information in the 2016 presidential campaign.

"They never used it," he said. "They rejected it. If there was collusion with the Russians, they would have used it."

The comments came hours after the Senate Judiciary Committee on Wednesday released the transcripts from a slate of interviews with participants of the now-infamous Trump Tower meeting in June of 2016 with Russian lawyer Natalia Veselnitskaya.
