“If they push forward without any attempt with hearing what she’s had to say, I’m not comfortable voting yes... We need to hear from her,” Flake told Politico. “And I don’t think I’m alone in this.”

Republican members of the committee initially released a statement Sunday calling Ford’s motive into question, and seemed ready to continue with Kavanaugh’s nomination as scheduled.

Flake’s statement is significant and could potentially throw Kavanaugh’s bid for the high court in jeopardy, as the GOP holds a slim 11-10 advantage on the judiciary committee.

Moreover, Flake’s voice is likely to weigh heavily on the minds of GOP moderates such as Sens. Susan Collins (R-Maine) and Lisa Murkowski (R-Alaska), who have not yet said how they intend to vote on Kavanaugh. Asked if the committee should proceed to vote this week as scheduled, Collins told CNN Sunday, “I’m going to be talking with my colleagues,” and declined to comment further.

Murkowski told CNN late Sunday that she was open to the idea of a delay on Kavanaugh’s confirmation. The senator told the outlet’s Steve Brusk that “if there are more questions that need to be asked and answered, then I think it would be appropriate for that time.”

“This is not something that came up during the hearings,” Murkowski said. “The hearings are now over. And if there is real substance to this, it demands a response.”
