Harvard law professor emeritus Alan Dershowitz said it is imperative Christine Blasey Ford testifies about her accusation against Supreme Court nominee Brett Kavanaugh, emphasizing there’s “not going to be very much” the FBI can do amid calls for an investigation into the decades-old allegation.

“She has to testify,” Dershowitz said while appearing on Fox News on Thursday. “As far as the FBI investigation is concerned, don’t count on that. There is not going to be very much the FBI can do. First of all, it is not an alleged federal crime. Second, the FBI doesn’t make credibility judgments.”
