A federal court has released a heavily redacted memo that outlines the Obama administration’s legal rationale for killing U.S. citizens overseas. During a three-month span in 2011, U.S. drone strikes killed four American citizens, including Muslim cleric Anwar al-Awlaki and, weeks later, his Denver-born 16-year-old son, Abdulrahman, in Yemen. The legal memo, kept secret by the administration until now, concludes the 2001 Authorization for Use of Military Force gave the U.S. government the authority to target al-Awlaki, who the administration claims had joined al-Qaeda. The memo was authored by former Obama Justice Department official David Barron, who was confirmed to the First Circuit Court of Appeals last month. We’ll discuss the memo’s release in detail later in the broadcast.
