Iowa Sen. Chuck Grassley will not lose any sleep over the confirmation hearing for Supreme Court nominee Neil Gorsuch.

The chairman of the Senate Judiciary Committee, who presided over the confirmation hearing on Tuesday, said he will hand over responsibilities to his colleague, North Carolina Sen. Thom Tillis at 8 p.m. so he can get to bed by 9 p.m., according to Politico.

It’s been a long day for Grassley — the second day of Gorsuch’s hearing began at 9:30 a.m. E.T.
