Input: The inspector general for the Environmental Protection Agency continues to dig into  EPA Administrator Scott Pruitt 's use of taxpayer money for travel.
According to an EPA memo cited by The Hill  the EPA's IG expanded the scope of its original investigation to include all of  Pruitt 's travel through 2017. The memo cites "additional Congressional requests."
The IG is looking at three main factors related to  Pruitt 's travel: "The frequency  cost and extent of the Administrator's travel â¦ Whether applicable EPA travel policies and procedures were followed for  Administrator Pruitt 's travel  as well as other EPA staff and security personnel traveling with or in advance of Administrator Pruitt â¦ [and] Whether EPA policies and procedures are sufficiently designed to prevent fraud  waste and abuse regarding the Administrator's travel."
According to the Washington Examiner  Sen. Tom Carper  D-Del.  requested that the EPA's IG look at  Pruitt 's four-day trip to Morocco last month that cost $40 000. The trip was intended to promote the use of natural gas.
The Washington Post reported in October that the EPA's IG was investigating  Pruitt 's travel habits in the first half of the year  which included non-commercial and military flights that cost more than $58 000.
