Does Huffington Post political reporter Sam Stein "booze up" his sources to get better information from them? That's what James O'Keefe alleges in a new video, reports Mediaite's Colby Hall. In the video, O'Keefe's Project Veritas goes undercover to record Stein's former Columbia University journalism professor as saying that Stein takes his sources out and plies them with alcohol to loosen their tongues. Tommy Christopher responds, "Saying that Sam goes out drinking with sources in DC is like saying he goes out breathing with them. People let their guard down in social situations. Stop the presses!” Stein denied the allegation in a phone interview with O'Keefe, and Hall recommends some skepticism considering O'Keefe's selective editing with his ACORN and NPR stings.
