Key Republican lawmakers are lining up to support embattled Environmental Protection Agency (EPA) Administrator Scott Pruitt Edward (Scott) Scott PruittJuan Williams: Swamp creature at the White House Science protections must be enforceable Conspicuous by their absence from the Republican Convention MORE amid numerous controversies about his spending and management.

The support comes as President Trump Donald John TrumpBubba Wallace to be driver of Michael Jordan, Denny Hamlin NASCAR team Graham: GOP will confirm Trump's Supreme Court nominee before the election Southwest Airlines, unions call for six-month extension of government aid MORE signaled he’s in no hurry to replace Pruitt, and as conservative commentators offer support on television and social media for an EPA chief who has sought to roll back regulations pursued by the Obama administration.

John Barrasso John Anthony BarrassoMurkowski: Supreme Court nominee should not be taken up before election Battle lines drawn on precedent in Supreme Court fight Sunday shows - Ruth Bader Ginsburg's death dominates MORE (R-Wyo.), who chairs the committee that oversees the EPA, indicated that he’s proud of Pruitt’s work at the agency and said he would hold off on any comment until the White House has thoroughly examined the issues at hand.

“Certain questions have been raised about internal operations of the agency and the administrator’s actions,” he said. “The White House has indicated it has taken on a formal review of these questions. I will wait for the outcome of that process.”

Barrasso, who was accompanied by Pruitt and Sen. Mike Enzi Michael (Mike) Bradley EnziChamber of Commerce endorses McSally for reelection Cynthia Lummis wins GOP Senate primary in Wyoming The Hill's Convention Report: Democrats gear up for Day Two of convention MORE (R-Wyo.) last week on a tour of a massive coal mine in Wyoming, also said the EPA chief had been “instrumental in returning the agency to its original mission.”

“American workers are benefiting from his reversal of punishing regulations,” he added.

“He’s following through with what the policies the president said he wanted to implement,” Sen. Mike Rounds Marion (Mike) Michael RoundsChamber of Commerce endorses McSally for reelection Senate GOP eyes early exit Senate Republicans signal openness to working with Biden MORE (R-S.D.) said Sunday on NBC’s “Meet the Press.”

Rounds said the criticisms of Pruitt amount to nitpicking.

“Oh, he has too big of a security detail? Is that suddenly the reason why you fire someone?” he asked.

That he uses a large security deal is just one of the issues for which Pruitt is under scrutiny.

Pruitt is under fire for renting a room from the wife of an energy lobbyist for $50 per day, a sum he only paid for the nights when he actually slept in the Capitol Hill condo.

His agency also gave raises to two top aides despite the White House rejecting Pruitt’s request, and Pruitt allegedly punished five officials for objecting to his spending and management decisions.

On Monday, The Atlantic reported that Sarah Greenwalt, Pruitt’s senior counsel, sent an internal email last month saying Pruitt wanted her to get a significant pay raise.

That contradicted what Pruitt told Fox News's Ed Henry last week, which was that he did not know that the EPA used a provision of the Safe Drinking Water Act to increase her pay after the White House didn’t approve it.

Those are in addition to months-long criticisms about his spending, including that he took frequent first-class flights and kept a security detail costing millions of dollars.

Toward the end of last week, it appeared Pruitt’s time at the EPA might be coming to an end. But that was before Trump offered public support, something that has been noted by Republicans in Congress.

“It looks like the president has gone out of his way to say he has confidence in him, so I just have to assume that he’s sticking around until we hear to the contrary,” said Senate Majority Whip John Cornyn John CornynTumultuous court battle upends fight for Senate Texas Democrats roll out first wave of planned digital ads as Election Day nears Calls grow for Biden to expand election map in final sprint MORE (R-Texas).

The president tweeted Saturday that Pruitt’s security costs are justified, his rent was “about market rate” and his travel expenses are “OK.” “Scott is doing a great job,” he concluded.

Even before Trump’s weekend tweet, allies of Pruitt were offering support.

Sen. James Inhofe (R-Okla.), who worked with Pruitt in his home state, heaped praise on him.

“Since being sworn in, Administrator Pruitt has been instrumental in carrying out President Trump’s deregulatory agenda at the EPA — ending the war on fossil fuels, repealing [the Clean Water Rule], exiting the Paris agreement and announcing new fuel emissions standards,” he said in a statement. “He’s been an effective member of the president’s team, and I look forward to continuing to work with him to restore the EPA to its proper size and scope.”

Pruitt still faces criticism and scrutiny.

The head of the Office of Government Ethics has scolded the EPA for its handling of the various potential ethical breaches.

“The American public needs to have confidence that ethics violations, as well as the appearance of ethics violations, are investigated and appropriately addressed,” acting Director David Apol wrote.

Apol doesn’t have the ability to punish Pruitt. But he said it is imperative that the EPA thoroughly investigate the controversies.

And on Sunday, three GOP senators added to the criticisms.

Sen.

“Stop acting like a chucklehead,” Sen. John Kennedy John Neely KennedyMORE (R-La.) implored on NBC’s “Face the Nation.”

“Why do you want to rent an apartment from a lobbyist for God’s sake? Stop leading with your chin. Now these are unforced errors. They are stupid,” Kennedy continued.
