Why does EPA Administrator Scott Pruitt still have a job? He's defiantly loyal to Donald Trump and effectively pushes his agenda

More than twenty Cabinet officers and high-level White House staffers have either resigned or have been fired from Donald Trump's administration in less than 18-months. So why does the scandal-plagued Administrator of the Environmental Protection Agency, Scott Pruitt, still have a job? Christa Slaton writes that much of Pruitt's durability is down to his Trumpian attitude towards his critics, denouncing attacks on him as “lies and half-truths”, his loyalty to Trump, and his effectiveness at rolling back EPA regulations.
