Senator Ron Wyden pushing for an overhaul of the laws governing the nation's intelligence community.
Wednesday, the Oregon Democrat introduced legislation that would, among other things, restrict the government's ability to conduct surveillance on law-abiding U.S. citizens.
The bill is being co-sponsored by Democratic Senators Mark Udall and Richard Blumenthal, and Republican Senator Rand Paul.
The bill would outlaw the bulk collection of email and phone records of American citizens and un-do a provision in the FISA Amendments Act that allows the government to obtain domestic communications without a warrant.
The bill would also install a constitutional advocate on the government's secret surveillance court and expand the ability of citizens to challenge surveillance laws in court.
Wyden says in the past the limits of technology served as a strong check on potential government overreach.
"Today, with technologies that make surveillance almost omnipresent, the key to preserving liberty and security is to embed new legal protections for law abiding citizens into the law," Wyden said.
The bill comes as the Senate prepares for a series of public hearings on surveillance laws.
