EPA inspector general to investigate Scott Pruitt's security detail on trips

• Latest in a string of investigations into Pruitt's travel spending
• Trips included Disneyland and attendance at sporting games

The Environmental Protection Agency's inspector general will investigate agency administrator Scott Pruitt's use of his official security detail on recent personal trips, the latest in a string of congressional, White House and internal investigations into his spending on security and travel.

The investigation comes at the request of Democratic senator Sheldon Whitehouse, he announced on Thursday, a month after he asked Inspector General Arthur Elkins to look into Pruitt's "unprecedented use" of his taxpayer-funded security detail documented in six weeks of obtained schedules and travel logs.
