From the Purpose and Summary: "H.R. 2048, the 'USA FREEDOM Act of 2015,' prohibits bulk collection of records under Section 215 of the USA PATRIOT [Providing Appropriate Tools Required to Intercept and Obstruct Terrorism] Act (Section 501 of the Foreign Intelligence Surveillance Act (FISA)), under the FISA Pen Register and Trap and Trace Device statute, and under National Security Letter (NSL) authorities. The Act creates a new program for the targeted collection of telephone metadata, provides greater privacy and civil liberties protections for Americans, expands existing congressional oversight provisions, and creates greater transparency of national security programs operated pursuant to FISA."
