Reid would be 'dumbfounded' if GOP blocked cybersecurity bill

Reid said the Senate has to act now on cybersecurity legislation to address the escalating cyberthreat the United States faces. He is expected to move to the cybersecurity bill later this week after the Senate wraps up votes on tax cut extensions.

"Unless we do something, it's not a question if there's going to be an attack that will be successful. The only question is when it will be," he said. "So that's why we have to do this."

The Aspen Institute's Homeland Security Group — which includes former Bush-appointed defense officials Michael Chertoff and Michael Hayden as members — urged the Senate on Tuesday to vote this week to take up the cybersecurity bill for debate on the floor.
