Nearly every time you see television from statements made in the House and Senate you are looking at a CSpan feed. Here is CSpan's copyright policy pertaining to statements made in the House and Senate.
Although C-SPAN is the only news media organization that regularly televises the legislative proceedings of the U.S. House and U.S. Senate, it does not hold a copyright in that video coverage. That government-produced video is in the public domain which means that it belongs to the American people and may be used without restrictions of any kind.
