Kash Patel, President Donald Trump’s choice to lead the FBI, is in high spirits after he was grilled by lawmakers this week on Capitol Hill.

Patel walked out of the Senate Judiciary Committee hearing late on Thursday night and told reporters that “it was a fantastic day” when asked how the thought the process was going.

The hearing heated up when Patel got into a tense back-and-forth with Minnesota Democratic Sen. Amy Klobuchar when she tried to smear him as being unqualified.

“Simply this: if the best attacks on me are going to be false accusations and grotesque mischaracterizations, the only thing this body is doing is defeating the credibility of the men and women at the FBI. I STOOD with them, here in this country, in every theater of war we have – I was on the ground in service,” Patel said.

“And any accusations that I would put political bias before the Constitution are grotesquely unfair and I will have you reminded I have been endorsed by over 300,000 law enforcement officers to become the next director of the FBI. Let’s ask them,” he added.
