New documents show higher price tag for Scott Pruitt's travel

EPA Administrator Pruitt's trip to Italy last year cost about $120,000

The higher costs – $30,553.98 – were related to his security detail, according to a document obtained through a Freedom of Information Act request and subsequent lawsuit by the Environmental Integrity Project, a non-partisan and non-profit watchdog group.

ABC News has reviewed the agency released single redacted page with the cost of Pruitt's security detail on his trip.

The cost of Pruitt's travel for 2017 is already under review by the agency's inspector general and the watchdog is also slated to look into the cost of his security detail.

EPA spokesman Jahan Wilcox said that the agency followed the same procedures for the G-7 trip as other administrators.

The EPA inspector general has said the office will review Pruitt's security expenditures but that it is not sure when it will be able to start looking into it because they have so many other investigations and reports pending.

But Wilcox said that's not the case and the agency has been cooperating through the proper channels.

"We do dispute that. We are responding through the proper channels which presently include EPA’s Office of General Counsel answering questions from the Government Accountability Office," he said in a statement.
