Greek American lobby in the United States
The Greek American lobby in the United States refers to the lobbyists, lawyers, and public relation specialists that work to promote U.S. interests in Greece by strengthening the bilateral relationship between the two countries. Such efforts include a decades long presence of public advocacy directed at the U.S. Congress, the Department of State, the White House, and other government institutions.
