The Troubled Journey of Major Hasan

Interning at Walter Reed
While training to be a doctor, Hasan reportedly opted for psychiatry after he fainted while witnessing a childbirth. He began interning at Walter Reed Army Medical Center in 2003. An officer who trained at about the same time remembers Hasan as being very vocal about being "a Muslim first and holding Shari'a law above the Constitution." Hasan once tried to preach against the "U.S. war against Islam" during a class on environmental health. He was also said to have been reprimanded for trying to convert patients to Islam. He argued for the right of Muslims to conscientiously object to fighting in predominantly Islamic countries like Iraq and Afghanistan.
