RAND PAUL VOWS FILIBUSTER:  He’s threatening to filibuster the Patriot Act reauthorization. The Act automatically expires on June 1, unless Congress reauthorizes it.  Senator Paul is opposed to section 215, which has been interpreted by some courts to allow NSA to collect so-called “metadata” on cell phone usage.  The U.S. Court of Appeals for the Second Circuit recently interpreted section 215 more narrowly.

Congress is slated to recess by Memorial Day.
