The FISA bill that permits warrantless NSA spying on American citizens was first enacted by Nancy Pelosi’s House in 2008, then signed into law by President Bush. The law provided for those powers to expire four years later, unless Congress approved renewal.
The law was first renewed in 2012 with the support of the Obama White House, this time for five years, without any reforms. When that five-year renewal was set to expire in 2018, Congress, this time backed by the Trump White House, passed a six-year reform-free renewal, requiring a new vote in 2024.
For the 2018 renewal, there was a mountain of evidence demonstrating abuse, which in turn gave rise to steadfast opposition to such a renewal from dozens of members of both parties (who were demanding, among other reforms, the addition of a warrant requirement for spying on Americans). As a result, then-Speaker Paul Ryan (R-WI) was forced to rely on dozens of Democratic representatives to secure FISA renewal.
Ryan accomplished this by working in close tandem with three key California Democrats: then-Minority Leader Nancy Pelosi, ranking Intelligence Committee member Adam Schiff, and Eric Swalwell (D-CA). That liberal trio led 65 House Democrats alongside 191 Republicans to vote to endow a President they were calling a Hitler-type fascist with virtually unlimited power to spy on Americans without warrants.
