In September 2017, the EPA spent what was thought to be $25,000 to build a soundproof booth for Pruitt to use in his office. The EPA's spokesperson said that this was to protect against hacking and eavesdropping. In March 2018, it was revealed that the cost of the booth was even higher than initially reported; actually almost $43,000. Christine Todd Whitman, EPA Administrator under George W. Bush, noted that there was already a secure phone booth in the building. In April 2018, the Government Accountability Office concluded that Pruitt's purchase of the $43,000 soundproof booth violated federal spending laws.
