JD Vance, a Republican senator from Ohio, proposed the Rail Safety Act in March.
"All of us were moved by the testimony of the witnesses" from East Palestine, Cruz said.
"We cannot undo the psychological, economic, and physical toll of the derailment in East Palestine," Vance noted, but "there will be another East Palestine in this country if we do not pass the Railway Safety Act."
"I earnestly hoped that we would reach a bipartisan consensus," Cruz said, but "this bill is overly and needlessly prescriptive."
Nonetheless, Cruz doubted the bill would pass the Senate with 60 votes, let alone the House.
