The U.S. citizen most commonly referred to in that context was Anwar al- Awlaki , who was killed in a U.S. drone strike in Yemen in 2011 under President Obama’s administration.

A few important details:

  • He was a U.S.-born cleric and extremist figure linked to al-Qaeda in the Arabian Peninsula.
  • His killing became a major legal and moral controversy because he was an American citizen.
  • Later U.S. statements also acknowledged other American citizens killed in drone strikes, but al-Awlaki was the one explicitly targeted.

If you meant the other Americans who died in Obama-era drone strikes , the names include Warren Weinstein and others mentioned in later government disclosures.
