Washington, March 9 (IANS) US President Barack Obama will nominate ex-Army general Robert Harding to head the Transportation Security Administration (TSA), Xinhua reported.

Harding's expertise will make him a 'tremendous asset in our ongoing efforts to bolster security and screening measures at our airports', a White House statement Monday quoted Obama as saying.

Harding served as director of operations at the Defence Intelligence Agency in the 1990s.

TSA was created after the 9/11 terror attacks in 2001, but the Obama administration was unable to find a chief for the agency.
