Christine Ford has leveled a serious accusation against Brett Kavanaugh, Donald Trump’s nominee to join the U.S. Supreme Court.

She intends to testify before the Senate Judiciary Committee, but wants the FBI to conduct a thorough investigation before she talks about her allegation: that Kavanaugh assaulted her sexually when they were teenagers.

The FBI can pull together all the evidence it needs to presumably determine whether Ford’s allegation holds up. Or it could come up empty. Or it could produce a result with no definitive answer.

Ford is asking that the FBI do its investigation before she talks.

If it delays Kavanaugh’s confirmation vote, so be it. If his confirmation — should it occur — come until after the court convenes its next judicial term, so be that, too.

The allegation is profoundly serious. Kavanaugh has denied categorically what the accuser has alleged. He is entitled to mount a vigorous defense. Ford, too, is entitled to get a fair and complete hearing of the allegation she has leveled against a man who wants to join the U.S. Supreme Court.
