A hearing aimed at letting Christine Blasey Ford testify about her claim of sexual assault against Supreme Court nominee Brett Kavanaugh was thrown into doubt on Tuesday, after committee aides said it wasn’t clear she would participate.

The Senate Judiciary Committee scheduled a public hearing Sept. 24, during which Kavanaugh and Ford were invited to testify, after Ford spoke on-the-record with The Washington Post about the alleged incident involving Kavanaugh that occurred during a party 36 years ago.
