On May 3, Eric Holder said that he had learned of the Gunwalker scandal “over the last few weeks”. But President Obama was aware of the scandal by March 22. That’s six weeks.
It’s just not plausible that the president would be aware of the scandal weeks before the attorney general, so I’m sure they will argue that six weeks counts as a “few weeks”. But that’s certainly not the impression that Holder was trying to give by saying “last few weeks” instead of “last couple of months”.
