While the agency did turn over documents last month detailing almost $68,000 in previously undisclosed travel costs for Pruitt during the seven months leading up to February, Gowdy said EPA officials have failed to produce the security waivers that Pruitt used to justify his purchase of premium tickets at taxpayer expense.
Administrator Pruitt is facing three separate investigations.
Committee Democrats, led by Rep. Elijah Cummings, D-Md., the ranking member of the panel, have asked Gowdy to subpoena the EPA for records and hold a hearing with Pruitt and top EPA officials. The letter quoted from the inside EPA paperwork nonetheless the total paperwork weren't made public. But there have been more questions and calls for investigation into whether it created a conflict of interest for Pruitt to rent from the wife of a lobbyist whose firm represented clients with interests before the EPA.
"These coins represent the agency", said Ronald Slotkin, who served as the director of the EPA's multimedia office until earlier this year.
Henry Barnet, who directs EPA's Office of Criminal Enforcement, Forensics and Training, told The Post that the goal was to provide "a buffer" between Pruitt and the public.
"They felt they could not protect him appropriately, based on the amount of times he was being recognized and the way that some members of the public were acting toward him", said Barnet, who added that he was "not aware of any physical confrontations" the administrator had faced since taking office.
"This development underscores the need for the Environment and Public Works Committee to conduct effective oversight of the EPA to answer the serious questions that have come to light in recent days concerning management and ethical conduct by the administrator and his staff", Carper and Whitehouse said in a joint statement.
The sidelining of Chmielewski is similar to the way other EPA officials, including career employees and political appointees, have been pushed aside after raising concerns about Pruitt's practices or use of agency resources and funds. They also acknowledged, though, that the materials might be incomplete. EPA spokeswoman Jahan Wilcox told the Daily News that the agency hasn't ordered any since Pruitt took over.
The records show that the agency's investigators reached out to the United States Postal Service, the Secret Service and the Federal Bureau of Investigation, as well as the Museum of Fine Arts in Boston, after Mr. Pruitt received a postcard that included the phrases "Get out while you still can, Scott", and "you are evil incarnite". "However, another view is that certain factions within EPA have justified the exorbitant taxpayer spending incurred by the Administrator's first-class travel and large entourage of security personnel through unsubstantiated claims about threats to his security, either at the direction of the Administrator himself or others in the agency".
President Donald Trump has also continued to stand by Pruitt publicly, tweeting his support over the weekend. Pruitt had planned to travel to Mexico this week, according to multiple agency officials, but has postponed the visit.
