C-SPAN

C-SPAN is a private, non-profit company, created in 1979 by the cable television industry as a public service. Their mission is to “provide public access to the political process. C-SPAN receives no government funding; operations are funded by fees paid by cable and satellite affiliates who carry C-SPAN programming.” So even though it’s not strictly a .gov site, it’s great for research.
C-SPAN supports initiatives that encourage greater public access to the court, including opening the court to electronic media. Access their Cameras In the Court Page here.
In addition to C-SPAN’s tv and radio schedules, you can look at their Firing U.S. Attorneys webpage. Or check out C-SPAN’s livestreams, podcasts and the video library. The video index lists the following areas: Congress, Defense/Security, Domestic/Social, Economy/Fiscal, International, Judiciary/Courts, Media/Press, Politics/Elections, Science/Technology, State/Local, White House/Executive and each index entry includes the title, date, location, summary, and length of the video. See Cal Ripken, Jr. talk about his book in the DOMESTIC/SOCIAL section. Watch Sarah Cohen & Gilbert Gaul, investigative reporters at the Washington Post, talk about their series, “Harvesting Cash,” on waste and abuse in federal farm subsidy programs in the MEDIA/PRESS section of the video library.
