EPA Administrator Scott Pruitt's expenses from March through May were released following a Freedom of Information request filed by Environmental Integrity Project, a non-profit watchdog group.
The records show Pruitt traveled home 10 times, typically leaving Washington on Fridays and returning on Mondays. Pruitt was either in Oklahoma or on trips that included stops there for nearly half of the days included in the three-month period, costing about USD 15,000.
EPA did not respond to requests for comment.
