Field Marshal Khalifa Haftar and his Libyan National Army (LNA) hired Linden Government Solutions, based in Houston, according to a foreign agent registration document released by the US Justice Department. The leader of the LNA is looking to gain international support for his bid to take over Libya.

According to an AP report Linden, which would receive about $2 million under the 13-month agreement, also will assist with “international coalition building, and general public relations” for the LNA.

Haftar is reported to have spoken to US President Donald Trump on the telephone. The two were said to have shared their vision of “Libya’s transition to a stable, democratic political system.”

The Linden executives leading the firm’s representation of Haftar and the LNA, Stephen Payne and Brian Ettinger, have extensive knowledge of Libya, the company said in a statement. Payne, Linden’s president, said he has been in communication with Haftar for the past five years, according to the statement.
