C-SPAN says its online feed of House floor action was briefly interrupted Thursday by programming for the Russian news network RT. The network says the problem was likely a routing issue, since RT is one of the networks that C-SPAN regularly monitors.
Spokesman Howard Mortman says C-SPAN’s website was replaced by RT for about 10 minutes. He says the network is “investigating and troubleshooting this occurrence.”
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.
