The federal government’s program for collecting and storing bulk telephony metadata is due to expire June 1, 2015.  That’s because Section 215 of the Patriot Act, which underlies the program, comes with a sunset provision requiring that the program end on that date if it is not reauthorized by Congress.  Although President Obama last year called for the program to be replaced by one in which phone companies retain the data themselves, there are increasing signals that the Administration will end up supporting reauthorization of the existing program ‒ quietly at first but more actively as the sunset date approaches.  The big question is whether a Republican-led Congress can muster the votes in the House and Senate to pass a reauthorization bill.  Meanwhile, decisions from the Second and D.C. Circuits in the next few months on the legality of the program are likely to influence the outcome one way or the other.
