At the Atlantic, Chris Good identifies some of the U.S. lobbyists who have registered to work for the Egyptian government. Filings required by the Foreign Agent Registration Act, and digitized and made searchable by Sunlight's joint project with ProPublica, the Foreign Lobbyist Influence Tracker, show that among foreign governments, Egypt has been one of the most prolific spenders. FARA filings show that the U.S.-Egyptian bilateral relation benefits American military contractors. The United States ships aid dollars to the Egyptian government, which in turn buys pricey items from American contractors, with deals often arranged with the help of U.S. lobbyists–who sometimes represent both the seller and the buyer. That's what PLM Group, a joint venture of the Podesta Group and the Livingston Group, did, as we reported with ProPublica in our initial release:

Lobbyists for Egypt had at least 279 contacts on military issues, the bulk of which occurred when PLM Group accompanied delegations of Egyptian military officers to meet members of Congress, administration officials and representatives from defense contractors including BAE Systems, General Dynamics, General Electric, Raytheon and Lockheed Martin. All five have done business with the Egyptian government, selling tanks, fighter jets, howitzers and radar arrays to its military. At the time of the meeting with the contractors, Podesta Group counted BAE Systems, General Dynamics and Lockheed Martin among its clients, while the Livingston Group represented Raytheon.
