Trump approves firing squad execution for Fort Hood attacker Nidal Hasan.
Context
What happened: President Donald Trump approved a firing squad execution for Nidal Hasan, the former army psychiatrist convicted in the 2009 Fort Hood shooting, a Pentagon spokesman said.
Key numbers: 13 people killed and 32 wounded in the 2009 attack. Hasan was sentenced to death in August 2013 on 45 counts. First US military execution since 1961.
Why it matters: Hasan would be the first US soldier executed by the military in more than 60 years. The Trump administration added firing squad, gas asphyxiation, and electrocution as execution methods in April.
