Investigators with the National Transportation Safety Board suspect a design flaw - undersize steel plates - and heavy loads of construction materials as the cause of the disaster Aug. 1, according to preliminary findings.
Democrats accused McCain of using a tragedy that killed 13 people and injured 145 others to make a political point.
Even Republican Sen. Norm Coleman of Minnesota said McCain was wrong.
