Sen. Richard Blumenthal, D-Conn., said Wednesday he and a group of bipartisan legislators are backing the ROBOCOP bill, which seeks to protect citizens from scam and spoof robocalls.

The Repeated Objectionable Bothering of Consumers on Phones Act, which was sponsored last week by Rep. Jackie Speier, D-Calif., would require phone companies to offer tools to consumers that would block potential scam robocalls at no extra cost. Blumenthal made his statement at the Senate Commerce, Science, and Transportation Committee hearing.
