Inside the contentious Trump-Biden appointee fight on the chemical safety board

The Trump-appointed head of the government’s chemical safety board is making her way to the exits amid high tensions with her colleagues, who were appointed by President Biden.


The U.S. Chemical Safety and Hazard Investigation Board, commonly known as the Chemical Safety Board (CSB), has been battling over a rule governing board operations that was approved by the exiting Chair Katherine Lemos, the Trump appointee.


Lemos announced her resignation on June 10, but she’s not actually leaving office for weeks and the fight with her colleagues is growing increasingly contentious.
