White House officials briefed key Senators Wednesday night on secret intelligence behind the Bergdahl-Taliban 5 swap. But the briefing did nothing to quell growing anger, reports the New York Times. Sen. Lindsey Graham warned that calls for impeachment would come quickly if President Obama released more Gitmo prisoners without complying with a law requiring him to give Congress 30 days advance notice, reports The Hill. Graham was one of the House prosecutors in the Clinton impeachment.
