"To see his family behind him ... it was anger, but if I were unjustly accused, that's how I would feel as well," he told "60 Minutes'" Scott Pelley.
Coons questioned Kavanaugh's temperament during the interview and said his reaction to questions by Democratic Sens. Dianne Feinstein and Amy Klobuchar about his drinking and behavior in high school "went over a line."
"He was clearly belligerent, aggressive, angry. And I thought there was a tough dynamic there. As I watched him, part of me thought, 'This is a man who believes that he did nothing wrong, and he's completely unjustly accused. And he's being railroaded. And he's furious about it,'" Coons said in the interview.
He also said that Kavanaugh’s partisan remarks bothered him, as well.
“I think his interaction with some of the members was a little too sharp. But the statement in the beginning I thought was pretty raw, but in keeping with someone who had been unjustly accused," Flake said.
Flake is not running for re-election and admitted that if he was, he would not have pushed for the one-week investigation into Ford’s charges.
Pending the outcome of the FBI probe, the vote on Kavanaugh’s nomination could come by the end of next week, unless the investigation uncovers something that could cause a further delay.
