Senate Judiciary Committee Chairman Chuck Grassley, R-Iowa, said Tuesday that Christine Blasey Ford, a California professor who accused Supreme Court nominee Brett Kavanaugh of sexual assault, has not yet accepted an invitation to testify before the panel.

Grassley told radio host Hugh Hewitt during an interview that the Senate Judiciary Committee contacted Ford three to four times via email over the last 36 hours regarding the upcoming public hearing, scheduled for Sept. 24. The committee, however, has not yet heard back from Ford, Grassley said.
