Watch: Lee Zeldin Administrator of the Environmental Protection Agency confirmation hearing

Lee Zeldin, a close and longtime ally of President-elect Donald Trump, has promised to dismantle “left wing” environmental regulations as the next leader of the EPA.

At his confirmation hearing he’ll face questions about Trump’s rejection of climate science and how the agency can adhere to its mission to protect human health and the environment if Zeldin’s focus is on economic growth and dismantling regulations.
