In April 2009, Mutassim Gadhafi, Khamis' brother and Libya's National Security Advisor, held a private meeting with Secretary of State Hillary Clinton upon his visit to the White House. With Mutassim at her side, Clinton told reporters at the time she was "very much looking forward" to broadening and strengthening the relationship between the two nations.
It was Clinton who said last week that after firing over a hundred missiles at Libyan government targets, the U.S. and its allies were handing over command of the no-fly zone over Libya to North Atlantic Treaty Organization.
"Gadhafi's troops have been pushed back, but they remain a serious threat to the safety of the Libyan people," she said.
