Washington (CNN) Democratic Rep. Mike Quigley on Wednesday described the whistleblower complaint about President Donald Trump's communications with Ukraine as "deeply disturbing" after viewing the document.

"I can't detail what it involves. Period," Quigley told CNN's Wolf Blitzer on "The Situation Room." "I will tell people that it is deeply disturbing. It reinforces the concerns that what we previously learned and I think it is a blueprint for what we still need to know."

Quigley asserted the whistleblower complaint "is the political equivalent" of Trump's claim during his 2016 presidential campaign that he could "stand in the middle of 5th Avenue and shoot somebody" without losing voters.

"What the President said during the campaign, he said he could shoot someone on the street and his base would stay with him. I guess what I read, to me, was the political equivalent of that: defying the constitution, committing a criminal act and thinking, 'Well I can get away with it,' " he said. "Some sort of bizarre cult of personality. Deeply disturbing what we read this morning. Alarming."

The whistleblower complaint -- which was hand-delivered to Capitol Hill on Wednesday for lawmakers to review -- deals, at least in part, with a phone call Trump had with Ukrainian President Volodymyr Zelensky on July 25. A transcript of the conversation released by the White House shows Trump repeatedly pushed Zelensky to investigate former Vice President Joe Biden and his son, Hunter.
