“This amendment asks for certain reporting to take place from the Pentagon and for them to work at ways of diminishing this reimbursement over time as we wind down our operations in Afghanistan,” said Corker, explaining the amendment from the Senate floor.

Corker, however, said his amendment was designed in such a way as to avoid further provocation against Pakistan.

“This amendment has been drafted in such a way so as to not further escalate tensions between us and the government of Pakistan,” said Corker, who also described it as a “good government” amendment.
