(CNN has withheld specific details about the size of Pruitt's security detail.) That security system, including an additional access card reader for the security office and an alarm in the office to alert agents, costs $15,780, the documents showed. EPA officials have considered using biometric security system, such as a fingerprint scanner, a source with knowledge told CNN. The number of government vehicles used by Pruitt's security detail will also grow, allowing each agent his or her own vehicle. Their letter states Pruitt's security costs "during his first quarter as EPA administrator is nearly double what the two previous administrators spent on security over that same timeframe."
