Just three days after he was narrowly confirmed to the U.S. Supreme Court despite facing allegations of sexual assault, Brett Kavanaugh is set to take his seat on the bench on Tuesday morning, solidifying a conservative majority for years to come.

Kavanaugh, 53, will join the eight other justices to hear arguments in cases involving a federal criminal sentencing law, bringing the nine-member court back up to full strength after the retirement of Anthony Kennedy in July.

Kavanaugh's confirmation gave Republican President Donald Trump a major victory, with his second lifetime appointee to the nation's highest judicial body. Neil Gorsuch joined the court last year.
