Senators are expected to vote Wednesday on a bill that would give Congress the power to use drones for surveillance.

The House passed the National Defense Authorization Act last week, and a vote on the Senate version is expected Tuesday.

The Senate is expected to adopt the legislation by late February.

The bill would give the executive branch the authority to conduct surveillance of American citizens without a warrant.

A judge would then issue a warrant that would allow the surveillance to continue.

The drones would not be used to collect any kind of data.

They would instead be used for intelligence gathering and counterterrorism operations.

The legislation is supported by the U.S. Chamber of Commerce, which has been a vocal advocate for the legislation.
