(New York Times) As the Senate edged toward a divisive filibuster vote on Chuck Hagel’s nomination to be defense secretary, Senator Ted Cruz, Republican of Texas, sat silent and satisfied in the corner of the chamber — his voice lost to laryngitis — as he absorbed what he had wrought in his mere seven weeks of Senate service.

Mr. Hagel, a former senator from Mr. Cruz’s own party, was about to be the victim of the first filibuster of a nominee to lead the Pentagon. The blockade was due in no small part to the very junior senator’s relentless pursuit of speeches, financial records or any other documents with Mr. Hagel’s name on them going back at least five years. Some Republicans praised the work of the brash newcomer, but others joined Democrats in saying that Mr. Cruz had gone too far.

Without naming names, Senator Barbara Boxer, Democrat of California, offered a biting label for the Texan’s accusatory crusade: McCarthyism.
