Republican U.S. Senator Jeff Flake of Arizona was deeply concerned by Judge Brett Kavanaugh's interactions with lawmakers during the recent Senate Judiciary Committee hearing.

Flake said he was “very troubled” by the Supreme Court nominee’s angry and lengthy opening statement. He called Kavanaugh’s interaction with lawmakers as “sharp and partisan,” which was also disturbing for him. He emphasized that there is no room for partisanship in the court.

“I hope I would sound that indignant if I felt I was unjustly maligned, but then it went on. And the interaction(s) with members were sharp and partisan and that concerns me,” said Flake.

He went on to say, “I tell myself give a little leeway because of what he’s been through. But on the other hand, we can’t have this on the court. We simply can’t.”

The senator from Arizona made his comment on Tuesday at The Atlantic Festival where he had conversations with Democratic Senator Chris Coons of Delaware and Jeffrey Rosen, the president of the National Constitution Center.

Flake is one of the key Republican senators who are undecided whether to support Kavanaugh’s appointment to the Supreme Court.

Flake delayed Senate vote on Kavanaugh’s nomination

On Friday, he played a critical role of delaying a vote on Kavanaugh’s nomination for a week. He demanded an FBI investigation into the sexual assault allegations against the Supreme Court nominee. Hid fellow Republicans agreed to his request.

Subsequently, President Donald Trump released a statement indicating that he “ordered the FBI to conduct a supplemental investigation to update Judge Kavanaugh’s file.”

Additionally, Trump made it clear that the scope of the investigation “must be limited and completed in less than one week.”

The FBI is expected to deliver the result of its investigation to the White House and the Senate on Wednesday.

Dr. Christine Blasey Ford, a clinical psychology professor accused Kavanaugh of sexually assaulting her when they were teenagers. She testified at the Senate hearing last Thursday. Two other women, Deborah Ramirez and Julie Swetnick accused the Supreme Court nominee of sexual misconduct.
