Environmental Protection Agency Administrator Scott Pruitt used a private email to conduct state business while he was attorney general in Oklahoma, the state confirmed Friday.

Fox 25 in Oklahoma City reported Friday that Pruitt used a private email to conduct state business during his time in office, which is not illegal in Oklahoma. However, it does directly contradict Pruitt's written and spoken testimony before the Senate Environment and Public Works Committee last month.

Pruitt told the committee that he had not used private email for state business. He also promised the senators he would only use his EPA email to conduct federal business.

Pruitt was confirmed earlier this month and is seen as a controversial choice to lead the EPA. As attorney general in Oklahoma, he sued the EPA multiple times.
