A Parting Gift

From the New York Times:

The administration has decided to deem the Shabab, the Islamist militant group in Somalia, to be part of the armed conflict that Congress authorized against the perpetrators of the Sept. 11, 2001, terrorist attacks, according to senior American officials. The move is intended to shore up the legal basis for an intensifying campaign of airstrikes and other counterterrorism operations, carried out largely in support of African Union and Somali government forces.

Notably, al-Shabab did not even exist in 2001.
