YouTube has launched 2 new channels in conjunction with Congress, one for the House of Representatives and one for the Senate. According to the YouTube blog, "as the 111th Congress kicks into gear, many of your elected representatives are starting their own YouTube channels. They're posting videos direct from their Washington offices, as well as clips of floor speeches and committee hearings alongside additional behind-the-scenes footage from Capitol Hill. " When you go to these channels you can click on a map of the US to find out if your representatives have any videos on YouTube.
