The USA Freedom Act appears to be the only chance that lawmakers have to prevent the laws from expiring, but it seems unlikely to get the 60 votes needed to overcome a procedural hurdle.
Virtually all Democrats are expected to support the bill, with the possible exception of Sen. Bill Nelson (D-Fla.), who opposed similar legislation last year, as are a handful of Republicans. The USA Freedom Act has five GOP co-sponsors: Sens. Mike Lee (Utah), Ted Cruz (Texas), Steve Daines (Mont.), Lisa Murkowski (Alaska) and Dean Heller (Nev.).
Rep. Cory Gardner (R-Colo.) also told The Hill this week he would support the bill, bringing the total number of supporters to at least 51, short of the 60 needed.
GOP leaders, including McConnell as well as Intelligence Committee Chairman Richard Burr (R-N.C.), have pledged to oppose the bill, and many GOP lawmakers are likely to join them.
