Two survivors of sexual assault who berated Sen. Jeff Flake in an elevator after he announced he would vote in favor of Brett Kavanaugh expressed relief that an FBI probe into sex assault allegations will take place.

Flake gave Kavanaugh's nomination a boost after the holdout Republican senator announced his support Friday morning following a day of harrowing testimony from Christine Blasey Ford who claims the judge sexually assaulted her.

Maria Gallagher, 23, and Ana Maria Archila had rushed after Flake in a Capitol Hill hallway and blocked the doors to the elevator Flake was in after he announced his decision.

Both woman revealed that they were survivors of sexual abuse, and accused Flake of silencing rape victims by announcing his support for Kavanaugh.

Archila pointed her finger at Flake while she appeared to keep the elevator door from closing.

'On Monday, I stood in front of your office,' Archila, co-executive director of the nonprofit Center for Popular Democracy Action, told Flake.

‘I told the story of my sexual assault. I told it because I recognized in Dr. Ford's story that she is telling the truth. What you are doing is allowing someone who actually violated a woman to sit on the Supreme Court.’

Gallagher shouted, through tears: 'I was sexually assaulted and nobody believed me.

'I didn't tell anyone, and you're telling all women that they don't matter, that they should just stay quiet because if they tell you what happened to them you are going to ignore them.'

"That's what happened to me, and that's what you are telling all women in America, that they don't matter," she said through tears.

After the heated exchange, Flake announced that he would advance Kavanaugh's nomination but only after after the FBI be allowed to investigate the allegations against Kavanaugh by Dr Blasey Ford.

Reacting to Flake's volte-face, Gallagher said she felt relieved that their voices had been heard and that an FBI investigation will take place.

She told the Daily Beast: ‘We all ran after him. We held open the elevator and I just started telling him why it was important and what had happened to me and why he should not let Brett Kavanaugh on the Supreme Court.

‘He wouldn’t meet my eyes, It made me very angry. He kept saying thank you and I’m sorry and wasn’t taking into account what his actions would be doing to millions of people and what this means for everyone.’

Gallagher claimed she never told anyone about her attack before – not even her own mother who had called her after seeing the clip on TV, according to the news site.

'This won’t be an easy conversation,' she said.

Last night Gallagher responded to Flake’s climbdown in a tweet along with a photo of her and Archina embracing.

‘I feel relieved that @JeffFlake seems to have heard my and @AnaMariaArchil2’s voices in the Senate elevator today,’ Gallagher tweeted along with a photo of her and Archina embracing.

‘We absolutely need an FBI investigation and for him and all Senators to vote NO. #StopKavanaugh.’

Archila is co-executive director of the nonprofit Center for Popular Democracy Action. The group sent a press release following the confrontation confirming it was Archila speaking on camera.

Flake gave Kavanaugh's nomination a major boost after the holdout Republican senator announced his support Friday morning. He later announced he would only support Kavanaugh's nomination if the FBI were allowed to investigate the allegations made against him by Christine Blasey Ford

Archila told the Associated Press she was sexually assaulted when she was 5 years old by a teenager when she and her family lived in Colombia. She said she didn't tell anyone before this week.

'I had planned to just talk to him nicely, but once when I saw that he was voting for Kavanaugh my niceties went out the window,' she said.

'What are you doing to our country? You are sending the wrong message you're saying that all of us who put our pain to the world to confront don't matter.'

After hearing about Flake's request, she said the sequence of events suggested their conversation helped move him.

‘What it tells me is that telling our stories and showing up can actually change their minds,' she said.

Before the exchange, Flake was returning to the committee room where he and 20 colleagues had heard hours of testimony Thursday from Christine Blasey Ford, a California psychology professor who told them Kavanaugh sexually assaulted her decades ago.

Kavanaugh strongly denied the allegation.

Flake had lobbied Republican leaders to give Ford the chance to speak. He was viewed as a possible 'no' vote on the panel and in the closely-divided Senate - until his morning announcement Friday.

That made the two women staking out his office angry and they confronted him when he tried to leave for Friday's hearing.

The fiery and emotional exchange was caught by TV cameras in what has become the most memorable moment in a day of high drama in the ongoing controversy.

Flake was later asked whether the elevator confrontation had swayed him.

'I can say this whole process has affected all of us,' he said. 'I can't pinpoint anything to say this is what caused me to come today to say let's postpone'.

He said it was 'remarkable' the number of people who saw Ford and were emboldened to come out and say what had happened to them.

'I've heard from close friends and I had no idea. That's important'.

President Donald Trump later agreed to order the FBI to open a supplemental background investigation into Kavanaugh that would be completed in a week.
