Tim Starks at CQ Today (sub. req. but the full article is here) reports that even top Republicans on the Intelligence Committees in both the House and Senate won't comment on what Rep. John Boehner said about FISA.  CREW believes Boehner may have violated federal law by leaking classified information and must be investigated.  While Boehner's office denies the charge, the actions of his colleagues who serve on the Intel committees is certainly interesting: 

Boehner's office mains that he was alluding to an earlier, January ruling by the secret court that had been previously discussed in public forums. Although details of that ruling are classified, administration officials have acknowledged that it was a decision placing the National Security Agency's warrantless wiretapping program under the purview of the FISA court.

When questioned by reporters, several lawmakers, including the top Republicans on the Senate and House Intelligence committees, Christopher S. Bond of Missouri and Peter Hoekstra of Michigan, respectively, have declined to say what Boehner was referring to on Fox.
