The amendment, penned by Sen. Bob CorkerBob CorkerSchumer puts GOP on notice over ObamaCare repeal Will Rubio vote for Tillerson? Senators wrestle with whether to back Tillerson MORE (R-Tenn.), comes as the near future of the relationship between Pakistan and the U.S. has been put into question as a result of a NATO airstrike on two Pakistani military outposts last week that took the life of 24 Pakistani soldiers.

“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.
