Pakistan has launched an aggressive lobbying effort led by Locke Lord Strategies to keep open a U.S. pipeline of billions in aid after al-Qaida leader Osama bin Laden was killed on Sunday.

Reuters reports that Locke Lord Strategies — the lobbying arm of Locke Lord Bissell & Liddell — has been retained by Pakistani President Asif Ali Zardari to fight accusations that Islamabad was complicit in giving refuge to bin Laden in a compound 50 miles outside of the country’s capital city and adjacent to its national military academy.
