The U.S. Department of Veterans Affairs and its secretary, Eric Shinseki, are under fire as reports surface about negligence at VA hospitals, including the death of around 40 military veterans in Phoenix who were placed on a “secret waiting list” to delay their care. Two administrators have been placed on official leave as the investigation continues.

The news has caused outcry across the country, particularly from veterans groups. Earlier this week the American Legion, the largest veterans organization in the country, called on Shinseki to resign. “It’s not something we do lightly. But we do so today because it is our responsibility as advocate for the men and women who have worn this nation’s uniform,” Daniel M. Dellinger, national commander of the American Legion, told CNN. Joining the Legion in that call was the group Concerned Veterans of America, a conservative veterans organization.
