Patton Boggs has been retained by the Interim Transitional National Council of Libya (TNC) to advise rebels fighting for U.S. support in their effort to topple longtime leader Moammar Gadhafi, according to The Hill.

The Am Law 100 lobbying powerhouse seeks to have the U.S. government recognize the TNC as Libya’s “legitimate government” in order to access billions in frozen funds accumulated by the Gadhafi regime overseas. Several European nations have already formally recognized the Libyan rebels’ claim to be the sole international representative for the North African country.
