Spokesman Howard Mortman said C-SPAN's website was replaced by RT for about 10 minutes. He said the network is "investigating and troubleshooting this occurrence."
The feed of the House floor cut to RT Thursday afternoon during the middle of a speech by Rep. Maxine Waters, D-Calif. Waters told the New York Times she found the timing of the incident "strange."

"I just think it's strange," Waters said. "At a time when our intelligence agencies are very confident and basically have confirmed that Russia hacked the D.N.C. and other political interests, and then we have, while I'm on the floor of the House, talking about Trump and Russia, I get interfered with and interrupted by Russia Today."
The programming glitch came hours after a power outage interrupted a Senate confirmation hearing for Kansas Rep. Mike Pompeo to head the CIA. The hearing reconvened in a different room.
