Was NBC's Gregory Drunk During Imus Interview?

NBC has denied that White House correspondent David Gregory was drunk when he was interviewed by radio/TV talk-show host Don Imus Thursday morning. Gregory, who is covering the president's visit to India, mysteriously appeared overcome by laughter as he chatted with Imus, at one time becoming nearly hysterical as he attempted to wish Imus "a nice day" in Hindi. "What's wrong with you?" Imus asked. Gregory replied, "I just think it's funny," Gregory replied with addtional laughter. Imus then reacted, "He is drunk." Conservative blogs pounced on the interview, with one writer asserting, "After this, it will be hard for this guy to have any credibility." In an odd exchange, Fox commentator Bill O'Reilly appeared to come to Gregory's defense as he showed the MSNBC video of the incident, remarking that Gregory was probaby "just exhausted." But liberal commentator Juan Williams, appearing on O'Reilly's program, insisted that Gregory had undermined his credibility and was attempting to "advance his career by being a clown." Later, NBC News spokesman Barbara Levin told reporters that Gregory was not drunk during the interview. "Do you listen to Imus? I mean this is what Imus does," Levin told the Boston Herald.
