Supreme Court nominee Brett Kavanaugh reportedly declined to answer some questions from White House aides during a mock interview last week in preparation for testimony over a sexual misconduct allegation made against him.

The Washington Post reported Saturday that White House aides pressed Kavanaugh about his sex life and drinking habits with the expectation that the judge will face uncomfortable questions during a Thursday hearing with the Senate Judiciary Committee.

Kavanaugh grew frustrated at some of those questions, and declined to answer some that he deemed too personal, the Post reported.

The news outlet reported that Kavanaugh condemned sexual assault, and avoided appearing to discredit Christine Blasey Ford, who has accused him of assaulting her during a 1980s high school party.

In an interview with the Post last week, Ford alleged that Kavanaugh pinned her to a bed, tried to remove her clothes and covered her mouth when she protested.

Kavanaugh has denied the allegations.

After days of back-and-forth negotiations, Ford agreed to testify on Thursday before the Senate Judiciary Committee.

Republicans are considering using a counsel, potentially a woman, to ask questions and avoid the optics of 11 male Republican senators questioning Ford.

It's unclear if Ford or Kavanaugh will testify first.
