The Supreme Court's newest Justice is making his debut for oral arguments.

FOX's Jared Halpern has more from Washington:

15 minutes into hearing his first arguments as a Supreme Court Justices, Neil Gorsuch asked attorneys a few questions, at one point, even apologizing for taking up so much time.

The case surrounds procedure in an employment discrimination claim.

Chief Justice John Roberts opened the session welcoming Gorsuch to the bench and wishing him a long and happy career.

Gorsuch's Senate confirmation returned the Supreme Court to nine Justices more than a year after the death of Justice Antonin Scalia.
