Excerpt:
A former inspector general for the Defense Department is calling on Congress to investigate and oversee the vetting process for Muslim clerics who are nominated to serve as U.S. military chaplains.
In a letter sent earlier this month to Sen. Dianne Feinstein, chairwoman of the Senate Intelligence Committee, former Inspector General Joseph Schmitz outlined what he believes is the potential risk to national security posed by the military's current chaplain vetting system.
Among the concerns Schmitz outlined in his letter, which was obtained by FoxNews.com, are:
— Reports that Army Maj. Nidal Hasan, accused of 13 counts of murder in last year's Fort Hood massacre, acted as a Muslim lay leader and received training from one of the approved civilian religious groups involved with the Defense Department chaplain program.
