Transportation Secretary Pete Buttigieg says he's taking steps to impose stronger regulations on freight trains hauling toxic chemicals, such as the one that derailed and exploded into flames near East Palestine, Ohio, earlier this month, forcing thousands of people to evacuate their homes and raising environmental and health concerns.
He's also calling on Congress to "untie" the agency's hands in regards to legislation that weakened the Department of Transportation's ability to enforce certain safety and accountability rules.
