Trump has kept Pruitt because he is pleased with Pruitt’s success at destroying regulations that protect the environment. Pruitt should be fired because of his corrupt behavior.
Here’s a roundup of articles on his policies, staff and personal behavior. There are so many, this only covers April 7-12:
That article has a good overview of all of the investigations concerning Pruitt.
“The prior head of Pruitt’s security detail, Eric Weese, was demoted last year after he refused Pruitt’s demand to use the lights and sirens on his government-owned SUV to get him through Washington traffic to the airport and dinner reservations.”
from the same article: “The EPA official who spoke to the AP said Perrotta also arranged the installation of a $43,000 soundproof phone booth for Pruitt’s office.
At least five EPA officials were placed on leave, reassigned or demoted after pushing back against spending requests such as a $100,000-a-month private jet membership, a bulletproof vehicle and $70,000 for furniture such as a bulletproof desk for the armed security officer always stationed inside the administrator’s office suite.”
“At least five officials at the Environmental Protection Agency, four of them high-ranking, were reassigned or demoted, or requested new jobs in the past year after they raised concerns about the spending and management of the agency’s administrator, Scott Pruitt.”
