Nominee's links to TSA contractors raise ethics concerns

Last week, President Obama nominated Army Maj. Gen. Robert Harding to head the Transportation Security Administration, but Harding's ties to several TSA contractors via Harding Security, a firm he founded in 2003, have raised ethics concerns.   "A review of Harding Security's business activities by CongressDaily showed that of 21 companies listed on the firm's Web site as its 'clients and partners,' several firms, including Lockheed Martin Corp., L-3 Communications, SAIC, CACI, QinetiQ and General Dynamics Corp., have done business with TSA."
