EPA employees reported that the doors to the floor in the EPA's headquarters containing Pruitt's office were frequently locked, and employees were required to have escorts while visiting the floor. Some EPA employees also reported being told not to bring cellphones or take notes in meetings with Pruitt. Pruitt was also accompanied by armed guards even while at EPA's headquarters, an unprecedented level of security for an EPA administrator. Pruitt also ended the longstanding practice of making public the appointments of the administrator and other top agency officials. These measures prompted critics to charge that Pruitt was running the agency in secret.
