MINNEAPOLIS (WCCO) — Since it was revealed that the National Security Administration collects phone data from millions of Americans, several bills have been introduced to address that issue.

Minnesota Sen. Al Franken introduced the USA Freedom Act in the Senate Thursday. He says the bill helps strike a balance between privacy and security.

“There needs to be more transparency,” Franken said.

He says the bill would require the NSA to obtain a warrant to access private data. It also allows Americans to see how much of their data has been stored.

The bill has already passed the House, where it gathered bipartisan support.
