Sen. Tom Coburn, R-Okla., said that “he might attempt to block the Senate from proceeding on a defense authorization agreement unless senators are allowed to offer amendments,” Roll Call reports.

“Managers of the National Defense Authorization Act are trying to push forward on a deal worked out between the House and the Senate without amendments so that an authorization could be signed into law before year’s end. Such a process, however, is not sitting well with all rank-and-file members, and particularly Coburn.”
