Christine Blasey Ford testified to the Senate Judiciary Committee Thursday that she is certain that Supreme Court nominee Brett Kavanaugh tried to cover her mouth to prevent her from screaming at a high school party and that it’s “absolutely not” a case of mistaken identity.

Asked by Feinstein how she could be so sure, Ford replied, “The same way that I’m sure I’m talking to you right now. Basic memory functions.”

When Feinstein asked if there is any chance that it’s a case of mistaken identity, Ford responded emphatically, “absolutely not.”

Judiciary Committee investigators spoke to two men earlier this week who say that they may have been involved in a sexual assault against Ford and think she may be confusing Kavanaugh with one of them.
