Secretary of Defense James Mattis spoke with members of the Senate Armed Services Committee on Friday, a conversation in which Sen. Lindsey Graham (R-S.C.) reports Mattis said he is mulling expanded U.S. military action in Africa in the wake of the attack in Niger that killed four U.S. soldiers. "The war is morphing," Graham said. "You're going to see more actions in Africa, not less; you're going to see more aggression by the United States toward our enemies, not less." Meanwhile, other lawmakers from both sides of the aisle have argued the Niger incident highlights the need to reconsider the broad war-making authority the executive branch has claimed in the post-9/11 era.
