Early in his tenure, Pruitt asked his security detail to use flashing lights and sirens when they were stuck in D.C. traffic. Eric Weese, the lead agent of his security detail, told Pruitt that flashing lights and sirens were only used in emergency circumstances. One of the instances included a trip to Pruitt's favorite French restaurant in D.C. Less than two weeks later, the lead agent was reassigned. Weese had also expressed a reluctance to sign off on requests that Pruitt needed to travel first class for security reasons. Agency staff questioned requests for a bulletproof sport utility vehicle, the construction of a special security booth in Pruitt's office, the tripling of the size of Pruitt's security detail, and the 24/7 work hours of his security detail. Reginald E. Allen, a career official at the EPA, was reassigned to an office within the EPA described as "an unmarked grave" after he objected to Pruitt's spending. Pruitt replaced Weese with Pasquale "Nino" Perrotta, a former Secret Service agent operating a private security company. Perrotta obtained a waiver to maintain outside employment while also heading Pruitt's security detail. Under Perrotta, there was a rapid expansion of Pruitt's security detail, as he signed off on various requests by Pruitt's team. Perrotta also wrote an email to five EPA officials which indicated that it was Pruitt's preference to use lights and sirens on his vehicle.
