Secretary of War Pete Hegseth said the execution of former Army Maj. Nidal Hasan will be made public when Hasan faces a firing squad at Fort Hood, Texas, on Dec. 3.

Hegseth made the announcement Thursday while discussing Hasan’s case, saying the execution would involve soldiers with rifles and that members of the public would be able to watch.

“We’ll make sure that people are able to watch it. That it’s public,” Hegseth said.

The Army has scheduled Hasan’s execution for 1 p.m. Central Time on Dec. 3 at Fort Hood, the same military installation where he carried out the 2009 massacre. President Donald Trump approved the death sentence on Oct. 2 after Hegseth recommended execution by firing squad.

Hasan, a former Army psychiatrist, opened fire inside a medical processing facility at Fort Hood on Nov. 5, 2009. Thirteen people were killed and 32 others were wounded in the attack.

Hasan was convicted by a military jury in 2013 and sentenced to death. During his court-martial, he acknowledged that he was responsible for the shooting and said he had “switched sides,” describing his actions as being connected to the war in Afghanistan.

If carried out as scheduled, Hasan’s execution would be the first military execution since 1961 and the first U.S. military firing-squad execution since World War II.

The Army has not publicly detailed every aspect of how the firing squad will be conducted. Hasan also retains the ability to pursue additional legal challenges that could delay the execution.
