Looks like the recent exploits of Comcast and Verizon have garnered the attention of Capitol Hill. Calls for Congressional hearings have been made. According to the AP:

Sens. Byron Dorgan, D-N.D., and Olympia Snowe, R-Maine, said the incidents involving several companies, including Comcast Corp., Verizon Wireless and AT&T Inc., have raised serious concerns over the companies' "power to discriminate against content."

They want the Senate Commerce, Science and Transportation Committee to investigate whether such incidents were based on legitimate business policies or unfair and anticompetitive practices and if more federal regulation is needed.
