U.S. Senate Judiciary Chairman Charles Grassley on Thursday sought a federal probe of Julie Swetnick, who accused Brett Kavanaugh of aggressive sexual behavior before his confirmation to the U.S. Supreme Court, and her lawyer Michael Avenatti. Grassley referred them to the Justice Department for criminal investigation related to "a potential conspiracy to provide materially false statements to Congress and obstruct a congressional committee investigation," according to a statement from his office. The Justice Department did not immediately respond to a request for comment on the referral.
