Washington (CNN) Rudy Giuliani tells CNN he has "no knowledge of any of that crap" in the newly released complaint from an American intelligence community whistleblower.

Asked Thursday morning about details from the complaint that multiple US officials were "deeply concerned" about his activities speaking with Ukrainian officials and nationals, Giuliani called the charge "total nonsense."

Giuliani spoke to CNN multiple times on Thursday morning from what he said was his room at the Trump International Hotel in Washington, DC. During one of those calls, the sound of the House Intelligence Committee hearing with acting Director of National Intelligence Joseph Maguire could be heard in the background.

Giuliani refuted claims included in the complaint that two State Department officials had spoken to him to "contain the damage" he was doing to US national security interests regarding his work with Ukraine.

"At no time did either one of them say they wanted to contain damage," Giuliani told CNN. "At no time did the State Department in communication with me ever relay any of that information you're talking about."
