— Administrator Pruitt (@EPAScottPruitt) June 10, 2017

After the meetings and the first day of the summit, Pruitt returned to Washington, D.C., to attend a Cabinet meeting at the White House.

Former EPA Administrator Gina McCarthy also had a meeting with the Vatican in 2015, according to remarks on the EPA website. Pruitt also said that the Canadian environmental minister met with them during the G-7.

\"This was a four-day exercise of focused efforts on decisions the United States had made on an international agreement that had a significant impact on this country,\" Pruitt said in the interview Thursday.

Audio of the KMOX interview was provided to ABC News by the Sierra Club.

The cost of Pruitt's travel for all of last year is under investigation by the EPA inspector general. The EPA has previously confirmed that Pruitt and his security detail fly first class for security reasons, citing the need to evacuate him quickly in the case of a threat.
