Wyden said he would lift his hold in exchange for a Senate floor vote on an amendment requiring the government to account for how many times Americans’ communications have been accepted, and another amendment prohibiting U.S. spy agencies from reviewing the communications of Americans ensnared in the program.

If that doesn’t go over, he’d lift the hold so the Senate could vote on brief extension of the act so his amendments and others could be fully debated next year.

“I’m willing to go along with a short-term extension as long as we have a chance in the early future, in 2013, to have a debate,” Wyden said.

"I think Congress should be extremely skeptical of any anti-leaks bills that threaten to encroach upon the freedom of the press, or that would reduce access to information that the public has a right to know," Wyden said in a floor statement publicly announcing his hold. "Without transparent and informed public debate on foreign policy and national security topics, American voters would be ill-equipped to elect the policymakers who make important decisions in these areas."
