U.S. Sen. Jeff Flake was making headlines inside and out of the hearing room Friday on Capitol Hill.

Just before the Senate Judiciary Committee voted on Brett Kavanaugh's Supreme Court nomination, Flake called for an FBI investigation into the sexual-assault accusations that Christine Blasey Ford made against Kavanaugh.

Flake voted to send the judge's nomination to the full Senate despite expressing uncertainty a day earlier, but he wouldn't support a floor vote for Kavanaugh before an investigation occurred.

As Flake stirred up controversy throughout the day, his name trended on Twitter. Some disagreed with his "yes" vote but applauded him for trying to get the FBI involved.

Others gave the credit to women who stopped Flake on Friday morning, pleading with him to listen to assault survivors.

Flake announced early Friday that he would vote yes, explaining his decision in a written statement.

“What I do know is that our system of justice affords a presumption of innocence to the accused, absent corroborating evidence,” he wrote. “That is what binds us to the rule of law."

"I will vote to confirm Judge Kavanaugh.”

Flake’s vote is crucial in getting Kavanaugh confirmed, so on Friday, many took to social media to express their frustrations.

‘He failed the moral test’

‘A coward’

After announcing he would back Kavanaugh, Flake was confronted by two female protesters outside the hearing room.

They told him they were sexual-assault survivors.

“What you are doing is allowing someone who actually violated a woman to sit in the Supreme Court,” one woman said to him in the emotional confrontation. “This is not tolerable. … What are you doing, sir?”

The other woman told Flake his vote has consequences for every woman in America.

“You’re telling all women that they don’t matter — that they should stay quiet because if they tell you what happened to them, you’re going to ignore them,” she said. “You’re saying that what happened to me doesn’t matter.”

Flake kept his head down and didn’t say a word back.

Supporting Flake

Despite all the criticism, some thanked Flake for his support of Kavanaugh.
