Supreme Court nominee Brett Kavanaugh on Monday wrote a letter calling the sexual assault allegations against him "false," "uncorroborated," and "grotesque." In the letter, written to Senate Judiciary Committee Chairman Chuck Grassley (R-Iowa) and Sen. Dianne Feinstein (D-Calif.), the committee's ranking member, Kavanaugh defended himself against new allegations from Deborah Ramirez, who says Kavanaugh exposed himself to her while they were in college.
