The Nickles Group is a Washington, D.C. lobbying firm that was established in 2005 by Don Nickles, formerly a Republican Senator from Oklahoma. He served in the Senate for 24 years, during which he was responsible for deregulation of natural gas, repealing the 1980s windfall profits tax, and repealing ergonomics regulation. He also fought health care reform during the Clinton administration. He was the author President Bush's 2003 economic growth package which cut capital gains and corporate dividend taxes to 15%.
The Nickels Group lobbies on health care policy, energy policy, telecommunications and media policy, budget, tax and economic policy. 
Nickles created a front group, the Copyright Alliance in 2007, which claims to speak for a broad range of copyright and intellectual property interests, with emphasis placed on creative individuals such as photographers and artists; it is, however, staffed by Nickles personnel, and follows an advocacy agenda similar to that of Nickle's telecom clients.
