Donald Trump has authorised an execution by firing squad just days after the botched execution of Christa Pike, who survived two lethal injections.

The US President has approved a firing squad execution for Army Major Nidal Malik Hasan, who carried out a shooting rampage at Fort Hood, Texas in 2009.

Pentagon spokesperson Sean Parnell wrote in a post on X following Trump’s approval: “Judgement day for Hasan has finally come.” The US military has not carried out the death penalty since 1961.

The Army secretary will decide a time and place for the execution, Parnell said.

Army psychiatrist Hasan walked into a medical building where soldiers were getting medical checkups and opened fire with a laser-sighted handgun. He killed 13 people and injured another 30 in his shooting spree.

During his trial he described himself as a soldier who had “switched sides,” carrying out the attack in an effort to stop the soldiers from going to Afghanistanto fight in the US war on terror.

An article published in May in the magazine Army Lawyer details how, despite Trump’s approval, Hasan could delay his execution – potentially for years – with a habeas corpus appeal in the civilian federal court system.

Death sentences are extremely rare in the US military justice system and executions are even rarer. Four men, including Hasan, are currently on the military’s death row at Fort Leavenworth, Kansas – the US military’s only maximum-security prison.
