AIA Lobbies Congress on Omnibus Lands Bill

Archaeo-bloggers David Gill and Paul Barford have implied that the efforts of the small businesses of the numismatic trade, the American Numismatic Association and collectors to get a fair shake from the U.S. State Department with the help of our elected representatives is somehow wrong. How ironic then that the Archaeological Institute of America is now also touting its own lobbying efforts and that of related groups on a pending Omnibus Lands Bill. See

Is it wrong for the AIA to lobby? Who has subsidized the time and effort behind this campaign? Public and private Universities? Someone else? And what of the AIA's recent campaigns in support of MOU's with Italy and Greece? The AIA does not register with the authorities so there is no way for the public to know.
