From a Senate staffer:

The press tables have been notably different than the Roberts hearing. During that hearing, the first day was packed to the walls; the second and third days were lighter, but still heavy; and the fourth day was like today (even the Dem staff sky box literally had the lights turned off). This time, it was packed on the first day; the second day was much lighter and some of the Senators were absent part of the day; the third day was worse; today was a ghost town.
