"Given the current budgetary constraints facing the United States and the recent strained relationship, the 112th Congress may question the return on such large investments in Pakistan, the second-largest US aid recipient," the bipartisan Congressional Research Service (CRS) said in a latest report.
"Lawmakers will seek the right balance between US aid expenditures to promote US national security interests in Pakistan and the region versus belt-tightening foreign aid cuts and accountability measures to address the lack of trust between the two governments," said the report ''Pakistan: US Foreign Assistance'', released on Tuesday.
According to the 44-page CRS report Pakistan is the second-ranking aid recipient of the US.
"Since 1948, the United States has pledged more than USD 30 billion in direct aid, about half for military assistance. Two-thirds of this total was appropriated in the post-9/11 era from Financial Year 2002-2010," the report said.
CRS said in the 2010 supplemental appropriations, Congress provided USD 349 million in military and economic assistance to Pakistan, USD 5 million more than the Administration's request.
