Sen. Hillary Clinton's staff had confirmed interviews earlier today with Fox News Channel, MSNBC and CNN. They were to be conducted after the President's State of the Union address. After wrapping an interview with Sen. Obama, CNN's Anderson Cooper said, "Senator Clinton agreed to talk with us. At the last minute she canceled. Her campaign is offering no explanation."

MSNBC and FNC confirm with TVNewser that Clinton canceled her appearances on those networks as well.

Sen. Clinton was interviewed by NBC's Brian Williams at 10:26pmET, that appears to have been her only TV interview of the night.
