Fox News Channel stuck with its regular schedule until 10 PM, when it switched to a special on the Benghazi investigation. FNC ran the guts of the WHCD — President Obama‘s speech followed by NBCU star Joel McHale — at midnight.

C-SPAN had the most comprehensive coverage of the annual Hollywood celebrity petting zoo for Washington press and the government officials they cover. Once again, C-SPAN’s coverage began with its traditional camera-trained-on-boom-mike coverage of celebs arriving at the hotel and the C-SPAN LeahyCam. Sadly C-SPAN is not rated by Nielsen, so those of you who watched on that network are lost to history.
