WASHINGTON (January 11, 2010)—A Pentagon review of the deadly Nov. 5 shooting rampage at Fort Hood’s Soldier Readiness Center that left 13 dead and 29 wounded fails to determine why accused gunman Maj. Nidal Malik Hasan was promoted in spite of worries over his competence, The Associated Press reported Monday.

While the doctors who oversaw Hasan's medical training voiced concerns about his strident views on Islam, he continued to get positive performance evaluations.

The review, obtained by The Associated Press, found that no one challenged his eligibility to hold a secret security clearance, even though his views raised doubt about his loyalty to the United States.

The report is to be delivered to Defense Secretary Robert Gates this week.

A Pentagon spokesman declined to comment on the review because it's not complete.
