The U.S. and other countries that seek to hand frozen assets of Col. Moammar Gadhafi's regime to rebels that seek to overthrow him face political and legal obstacles that could slow the delivery of funds.

Secretary of State Hillary Clinton on Thursday said the Obama administration was working with Congress to pass legislation allowing the Treasury Department to release Libyan assets that it froze in response to the Libyan leader's crackdown on protesters. The U.S. has frozen more than $34 billion of assets related to the Gadhafi regime; billions of dollars more have been frozen elsewhere.
