The history is more complicated than that. Obama originally proposed rules for widening the definition of hazardous trains and requiring upgraded brakes. This version didn't get enacted. It was weakened after a lot of lobbying eg trains carrying oil and gas were no longer "hazardous". Trump did remove this rule in 2018. But we're in 2023 now when Biden was sworn in over 2 years ago. Did Biden or Buttigieg re-institute these rules? No. This problem is beyond politics. Both parties serve corporate interests. Republicans just go a little further on the deregulation train (pun intended). Look at Biden and Congress united behind hobbling the rail workers strike. Those rail workers were wanting to strike in part due to safety issues. Buttigieg is a McKinsey alum. He's part of the system that creates this problem. Don't think this is just a few bad apples. It isn't. It's a systemic problem.
