Protecting Americans from Unauthorized Surveillance Act

This bill creates a new FISA Oversight Office within the Department of Justice to review surveillance applications and challenge those that fail to meet legal standards for probable cause. The office would evaluate applications, file motions with the court when probable cause is insufficient, and receive all relevant evidence from federal investigators. Additionally, the bill requires the Foreign Intelligence Surveillance Court to appoint an independent amicus curiae to assist in reviewing surveillance applications. These changes aim to increase oversight and transparency in government surveillance programs while maintaining the existing legal framework.
