The U.S. Environmental Protection Agency (EPA) has announced Lee Zeldin was sworn in as the 17 th administrator of the agency. In the role, Zeldin will work closely with career officials at the agency to fulfill the agency’s mission to protect human health and the environment.

The Senate on Wednesday confirmed former New York Rep. Lee Zeldin to be EPA administrator along mostly partisan lines. Why it matters: Zeldin, with little experience in environmental policymaking, will spearhead the Trump administration's push to reverse former President Biden's climate regulations.

The former New York congressman has little experience in environmental policy. He is expected to follow orders to weaken climate rules.
