Defense Secretary Mark Esper testifies to the Senate Armed Services Committee about the budget, Wednesday, March 4, 2020, on Capitol Hill in Washington. An uptick in Taliban attacks against Afghan forces that prompted a retaliatory U.S. airstrike has underscored the fragility of the peace deal between the Trump administration and the group. Esper told the Senate hearing that the Taliban are honoring the agreement by not attacking U.S. and coalition forces, “but not in terms of sustaining the reduction in violence.” (AP Photo/Jacquelyn Martin)
