Bush administration 'spent three months reviewing ports deal'
"We're not aware of a single national security concern raised recently that was not part of the multi-agency, three-month review," Deputy Treasury Secretary Robert Kimmitt told a Senate Armed Services Committee briefing.
Representatives of key agencies that investigated the port deal - but not the heads of the various departments - sought to reassure senators just hours after US President George W Bush declared "people don't need to worry about security."
