Judicial advocacy organizations are taking to the airwaves with competing campaigns as the Senate grapples with how to proceed with the nomination of Brett Kavanaugh to the Supreme Court after a California professor accused him of sexual assault more than 30 years ago.

Judicial Crisis Network, a group that has spent millions in support of Kavanaugh’s nomination, is planning to launch a $1.5 million TV ad campaign that features a longtime friend of Kavanaugh’s, a spokeswoman for the group said.
