"Why not then?" Pelley asked.

"Because this isn't about politics," the senator responded.

Heitkamp announced her intention to vote "no" on Thursday, pointing to allegations of sexual misconduct against Kavanaugh, and questioning his judicial temperament.

On "60 Minutes," she highlighted the testimony of Christine Blasey Ford, who told the Senate Judiciary Committee that she was "100 percent" certain Kavanaugh pinned her to a bed, groped her and attempted to remove her clothes during a high school party in the 1980s. Kavanaugh has denied the allegations.

"My judgment on her experience is based on a lot of experience working with domestic assault victims, domestic violence victims," Heitkamp said.

"And the experiences that have been shared over and over in my time as attorney general and now coming to the Senate as people have described their experience, and for me it does not appear that he's somebody who should be given a lifetime appointment to the most important court in the world," she added.

Heitkamp argued that that even if senators did not believe there was evidence to corroborate Ford's claims, Kavanaugh's testimony blasting Democrats for conducting an "orchestrated political hit" against him provided additional reason to oppose his confirmation.

The Senate confirmed Kavanaugh on Saturday afternoon in a 50-48 vote, with one GOP senator absent and another voting "present." Every Democrat opposed Kavanaugh's nomination except for Sen.

The bitter fight over Kavanaugh’s confirmation came after multiple women accused the judge of sexual misconduct. Kavanaugh and Ford testified late last month over allegations that he sexually assaulted her during a party in the 1980s

A supplemental FBI background investigation found no corroboration of the claims, Republicans said, while Democrats argued that the review of the allegations was too brief and failed to interview key witnesses.
