Hunton Andrews Kurth made no immediate comment on Wednesday following an announcement that a former partner, William Wehrum, is leaving his post as assistant administrator for air and radiation with the Environmental Protection Agency.

Wehrum was a partner with predecessor firm Hunton & Williams and head of the firm’s administrative law group before his confirmation to serve as an EPA official in 2017. He has been the subject of sustained scrutiny by Democrats on the U.S. House Committee on Energy and Commerce into actions he has taken at the agency that allegedly favored his and his law firm’s clients.
