US President Barack Obama is most likely to sign the bill for providing USD 7.5 billion aid to Pakistan into law on Friday . Enhanced Partnership with Pakistan Act of 2009 - popular as Kerry-Lugar Bill - would be signed by the US President before the expiry of the mandatory 10 days time after it being sent to him, White House Spokesman Robert Gibbs told reporters during his daily press briefing. The US Congress yesterday issued an "explanatory statement" in an effort to placate the concerns of Pakistan on the aid bill which says that the legislation does not seek in any way to compromise Islamabad's sovereignty and impinge on its security interests.
