As the national debate over airport screening practices intensifies, little attention has paid to the increasing lobbying power the manufacturers of full body scanning machines have in Washington. USA Today reports L3 Communications has spent $4.3 million on lobbying, up from $2.1 million in 2005. L3 has sold nearly $40 million worth of machines to the federal government. Lobbyists for L3 have included Linda Daschle, the wife of former U.S. Senate majority leader Tom Daschle. Meanwhile, Rapiscan Systems has spent more than $270,000 on lobbying so far this year, compared with $80,000 five years earlier. The company made headlines last year when it hired former U.S. Homeland Security Secretary Michael Chertoff, who has become a prominent proponent of body scanners. Deepak Chopra, the CEO of Rapiscan’s parent company, recently traveled with President Obama on his three-day trip to India.
