The latest person to take the well-traveled path from Capitol Hill to greater riches on K Street is Dan Turton, floor assistant for outgoing House Minority Leader Richard Gephardt (D- Mo.). Turton has singed up with Timmons & Co., which has also snapped up Alan Hoffman, chief of staff to Sen. Joseph Biden (D-Del.). At a grave time for the airline industry, meanwhile, American Airlines has tapped Daniel Elwell to serve as managing director of international and governmental affairs. Taking a more unconventional path to the lobbying industry, Elwell is a veteran company pilot. That led to the inevitable quip in a company press release that he is "equally at ease navigating a bill through Congress as he is a 767 across the country." Fleishman-Hillard, meanwhile, has signed up the former drug czar, retired Gen. Barry McCaffrey, to launch a new homeland security practice at the public relations behemoth. Three members of the firm's international advisory board - former Defense Secretary William Cohen, ex-Speaker Newt Gingrich (R-Ga.) and former Health and Human Services Secretary Louis Sullivan - will provide "strategic counsel"to the new practice. And Thomas Wheeler, president and CEO of the Cellular Telecommunications & Internet Association, has been elected president of the board of directors of the Foundation for the National Archives.
