the U.S. In June, after visiting one of the detention facilities near the border in San Diego, Harris became the first senator to demand Nielsen's resignation. In the September and October Brett Kavanaugh Supreme Court confirmation hearings, Harris questioned Brett Kavanaugh about a meeting he may have had regarding the Mueller Investigation with a member of Kasowitz Benson Torres, the law firm founded by the President's personal attorney Marc Kasowitz. Kavanaugh was unable to answer and repeatedly deflected. Harris also participated in questioning the FBI director's limited scope of the investigation on Kavanaugh regarding allegations of sexual assault. She voted against his confirmation.

Harris later called for Barr to resign, and accused him of refusing to answer her questions because he could open himself up to perjury, and stating his responses disqualified him from serving as U.S. attorney general. Two days later, Harris demanded again that the Department of Justice inspector general Michael E. Horowitz investigate whether Attorney General Barr
