Not sure what the outrage is about?
First the Obama administration doesn't believe in such thing as U.S. Islamic Jihadists -- which is why Obama had Major Hasan declared a committer of workplace violence. Second the FBI hasn't found any evidence that the Islamic terrorist was in fact an Islamic Terrorist. So Biden just went massively off the White House script for such things in general and for this event in particular. It is in other words a typically delicious incident of Biden being . . . Biden.
This then is the man that many Dems are trying like hell to get to commit to running for the presidency. Oh, and I do hope that Joe does just exactly that! The opportunity for laughter would be endless.
