Curiouser and curiouser!

This video features a March 2011 interview with Obama saying he heard on "the news" about Fast and Furious, then a Congressional Hearing in May 2011 in which Attorney General Holder says he just heard about it in "the last few weeks." Well, I guess from March to May qualifies as a "few weeks," but who knew first, Obama or Holder? Or, did they both know at the same time, because they agreed on the plan before it was initiated? How did Obama know in March that Holder knew nothing about the plan? Doesn't that indicate that he had talked with Holder about it before his March interview?
