President Donald Trump has maintained full support of his Supreme Court nominee, and he clearly views Mr. Kavanaugh’s confirmation as a top priority, regardless of these accusations. Ms. Conway is a tireless, passionate and often fanciful defender of President Donald Trump, and “Fox & Friends” is the go-to venue for “alternative facts” in that pursuit. Yet Ms. Conway sent an unmistakable message to Senate leadership, perhaps even to her boss and certainly to the American people that Ms. Ford’s charges are to be taken seriously. It’s a shame that Senate Judiciary Chairman Chuck Grassley or Senate Majority Leader Mitch McConnell did not arrive at that conclusion first. Of course, it’s foolish for the committee to vote on the Kavanaugh nomination on Thursday with such a serious allegation unaddressed by the Senate. It is not just unfair to Ms. Ford — and to Mr. Kavanaugh for that matter — but to all Americans who have a right to expect the Senate to have a full and fair evaluation of the nominee before deciding whether to approve this lifetime appointment to the nation’s highest court. It has already failed to do so when it comes to a reasonable vetting of Mr. Kavanaugh’s judicial views; to fail again on a topic of visceral concern to Americans of both sexes would be inexcusable.
