In a letter to FBI Director Christopher Wray and Justice Department Criminal Division Chief John Cronan, the group of lawmakers argue that Pruitt repeatedly violated federal anti-corruption laws by using his position for personal gain, according to The Associated Press.
The letter cites reports that Pruitt attempted to secure a Chick-fil-A franchise for his wife, and paid $50 a night to rent a condo from the wife of a lobbyist who lobbied the EPA.
With regard to the Democratic letter, an EPA spokesperson referred requests for comment to Pruitt's outside counsel.
"Scott Pruitt is doing a great job within the walls of the EPA", President Trump said as he left the White House for the G7 summit in Canada.
Pruitt and EPA spokespeople have generally denied any wrongdoing.
For his part, Pruitt sought to laugh off the controversy this week over his using government resources to seek a "business opportunity" with the fast-food fried chicken chain whose owners are known for supporting conservative Christian causes, including outspoken opposition to same-sex marriage.
In addition, Beyer is asking the Federal Bureau of Investigation to look at the condo deal Pruitt made with a lobbyist's wife, securing a $50-per-night below-market-rate room for himself while in Washington. The senators asked EPA Inspector General Arthur Elkins Jr.to investigate the agency's compliance with open-records laws in the matter.
This week, congressional Democrats released the transcript of an interview in which Millan Hupp, a close aide to Pruitt, said the administrator had her carry out personal errands, including researching the purchase of an old mattress from the Trump International Hotel.
The lawmakers' letter also notes Pruitt's contact previous year with the leader of a NY nonprofit on his wife's behalf.
"We write to you with grave concerns that".
An EPA spokesperson told the Daily Beast, "EPA will not be commenting on anonymous sources who are working to distract Americans from Administrator Pruitt's accomplishments on regulatory certainty and environmental stewardship".
