J.D. Vance, the freshman senator from Ohio, is in the spotlight for the first time in his tenure as he responds to the train derailment and its aftermath.
An overheating wheel bearing set off an audible alarm on the train before it derailed this month, according to a preliminary report from the National Transportation Safety Board.
The former president has attacked President Biden over his administration’s handling of the train derailment disaster, even as his own environmental policies while in office have been criticized.
