Oregon Second District Congressman Greg Walden told the Energy and Commerce Subcommittee on Communications and Technology that Congress must stop bad robocalls from burdening Americans.  The Hood River Congressman made his comments during markup for the Stopping Bad Robocalls Act.  The bill would require phone carriers to implement call authentication technology so that consumers can trust their caller ID at no cost of their own.   The bill also includes provisions that would help carriers in rural America implement this new technology and would ensure that consumers have safeguards to prevent important calls from being blocked.
