A group of privacy-focused lawmakers on Thursday introduced legislation to reform a set of controversial surveillance authorities set to expire in March, setting up ambitious goalposts in the upcoming battle over whether Congress should pare down the government's ability to spy on people in the U.S.

The bill, from a bipartisan and bicameral coalition, would narrow down the kinds of information the government is allowed to collect without a warrant and officially shut down its ability to collect phone records on millions of Americans.

The Safeguarding Americans’ Private Records Act seeks to capitalize on a wave of renewed bipartisan interest in the Foreign Intelligence Surveillance Court (FISA court), an instrumental part of the country's intelligence-gathering and national security operations.

It sets the stage for a bipartisan coalition between Trump allies, who have criticized the FISA court as part of a deeply political battle over whether the FBI exhibited bias against Trump, and progressives who want to reform government surveillance authorities.

The legislation would permanently end the phone records program disclosed by whistleblower Edward Snowden, which shuttered last year amid technical difficulties. It would also officially prohibit intelligence agencies from collecting geolocation information without a warrant.

Significantly, it would ensure independent attorneys have access to the proceedings of the FISA court.

The government filed 1,117 warrant applications to the FISA court last year, including 1,081 that requested electronic surveillance.

Congress is facing a mid-March deadline to extend three expiring surveillance authorities.

"The surveillance capabilities intended to keep us safe from foreign threats have all too often trampled on Americans’ Fourth Amendment rights to due process," Josh Withrow, a senior policy analyst for conservative group FreedomWorks, said in a statement. "The Safeguarding Americans’ Private Records Act would be an enormous step forward in securing those rights."
