Trump orders firing squad for Fort Hood gunman who killed 13.
Context
What happened: President Donald Trump ordered a firing squad execution for Nidal Hasan, the former US Army psychiatrist convicted in the 2009 Fort Hood, Texas shooting that killed 13 people, the Pentagon said.
Key numbers: 13 killed, 32 wounded in 2009. Hasan convicted of 45 counts in August 2013. He is 56. First military execution since 1961 if carried out.
Why it matters: The order follows the administration's expansion of federal execution methods, which officials linked to difficulties obtaining lethal injection drugs. Death Penalty Action opposed the decision.
