Sen. David Vitter, R-La., says that he has caught the Environmental Protection Agency in a lie about the extent to which their officials are breaking transparency rules by using non-official emails to conduct government business.

“EPA should start owning up to the facts piling up before them,” Vitter said as his office announced that the “EPA lied” by saying that a regional administrator was not using one of the banned email accounts. “Their blatant disregard for proper procedure and transparency is now being regularly exposed, and EPA’s leadership must be held accountable.”
