The decision marks a reversal for the administration, which had argued that Kavanaugh had already been vetted.
Brett Kavanaugh's nomination to a lifetime seat on the U.S. Supreme Court hung in the balance on Friday after a jarring and emotional hearing into sexual misconduct allegations against him that gripped the country and reflected the nation's larger political divide.
There was initially expected to be a procedural vote on the Senate floor on Saturday, with Republican leaders' looking to hold a final Senate vote early next week, but given the concerns from Flake and what transpired in the Judiciary Committee Friday, that could now change.
President Trump said in a statement that he had ordered the bureau to "conduct a supplemental investigation to update Judge Kavanaugh's file" and added that the update "must be limited in scope and completed in less than one week".
The Senate Judiciary Committee was set to vote on advancing the Supreme Court nomination of Brett Kavanaugh to the Senate floor.
"Well, it's not up to you", said Blumenthal. Susan Collins of ME and Lisa Murkowski of Alaska - and two Democrats in red states - Sens.
Kavanaugh reiterated that he had wanted a Senate hearing on the allegations against him. And five days of hearings, during which Judge Kavanaugh testified for almost 40 hours.
During Thursday's hearing, Democrats repeatedly peppered Kavanaugh with questions about whether he would support an FBI investigation. Democrats have been eyeing him as a possible "no" vote, leaving many surprised to see him announce on Friday morning that he backed the judge.
Late Thursday, the magazine of the Jesuit religious order in the United States withdrew its endorsement of Kavanaugh, saying the nomination was no longer in the interests of the country and "should be withdrawn". Another, Julie Swetnick, said in a declaration that Kavanaugh was physically abusive toward girls in high school and present at a house party in 1982 where she says she was the victim of a "gang" rape.
Flake then returned and announced he would vote to advance Kavanaugh's nomination to the full Senate with the understanding that his request would be honored. But if Flake and other Republicans demand it, President Donald Trump may have no choice.
Actress Alyssa Milano speaks during a rally in front of the US Supreme Court September 28, 2018 in Washington, DC. But-in a politically sound but preposterous twist-Republican leadership and spokespeople are also professing to believe Ford's story about her assault, with one caveat: She must be misremembering the person (s) who did it. West Virginia Democratic Senator Joe Manchin said he supported Flake's call to push off a full Senate vote until the FBI investigates Ford's allegation.
The case made by Democrats and outside groups goes beyond Judge.
Kavanaugh is a former top aide in Bush's administration.
The implication from Flake was that he will vote no if the investigation doesn't come to fruition and that the vote was to happen early next week as initially planned.
The committee's staffers and investigators have been dealing with other allegations, according to transcripts released by the Judiciary panel, including ones they and Kavanaugh have concluded were false. The memory - and Kavanaugh's laughter during the act - was "locked" in her brain, she said: "100 percent".
