Since Justice Thomas, there has been an expectation that Republican nominees for the Supreme Court lie during their confirmation hearings. Thomas pretending that he wasn’t sexually harassing Anita Hill. George W. Bush’s nominees pretending that they didn’t have an opinion on roe. That kept going under Trump.
But yeah. Kavanaugh is worse. Just brazenly lying about who he talked to about the Muller investigation. Knowable facts. At this point, not only should the Senate not support him, the House should probably impeach him.
