I haven't been able to get a copy of the exact text yet. But the Republican counter-amendment on the floor is truly amazing. It would strip of his or her security access any senator who repeated a statement by an FBI agent which was subsequently used as "propaganda" by America's enemies. In other words, the law is targeted at Sen. Durbin, making it against the law to say what he said a month ago.
(ed.note: If anyone can send me a copy of the text, I'd appreciate it.)
Late Update: Here is the text of the so-called 'Frist Amendment': "Any federal officeholder who makes reference to a classified Federal Bureau of Investigation report on the floor of the United States Senate, or any federal officeholder that makes a statement based on a FBI agent's comments which is used as propaganda by terrorist organizations thereby putting our servicemen and women at risk, shall not be permitted access to such information or to hold a security clearance for access to such information."
