President-elect Trump’s choice to head the Environmental Protection Agency visited Capitol Hill Tuesday to meet with the incoming and outgoing chairmen of the Senate environment committee to discuss his confirmation.

Outgoing Environment and Public Works Committee Chairman Sen. James Inhofe, R-Okla, who is retiring, escorted Scott Pruitt, Trump’s EPA nominee and Oklahoma attorney general, to meet with the new chairman, Sen. John Barrasso, R-Wyo. It was the first time Pruitt visited Capitol Hill after being nominated to lead the agency. The committee will be key to confirming Pruitt as EPA administrator. The Senate controls approval of all Cabinet nominations.
