Sen. Susan Collins, R-Maine, on Monday called on Senate Judiciary Committee Chairman Chuck Grassley to let Supreme Court nominee Brett Kavanaugh and the woman accusing him of sexual assault in the 1980s, Christine Blasey Ford, testify under oath before the committee before the Senate votes on Kavanaugh’s nomination.

“Professor Ford and Judge Kavanaugh should both testify under oath before the Judiciary Committee,” Collins tweeted Monday.
