PRUITT IN THE HOUSE: Environmental Protection Agency (EPA) chief 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 faced two House subcommittees Thursday for more than six hours of testimony.

The hearings ran the gamut, with Democrats focusing on his scandals in ethics and spending and Republicans focusing on highlighting policies they like.

Here are some key takeaways.

1) Critics didn't appear to deliver a damaging blow.

Pruitt headed into the hearings with mounting controversies and growing calls for him to resign. But the hearings lacked some of the expected fireworks. And Pruitt had explanations ready for most of the spending and ethical questions that lawmakers presented Thursday.

"Facts are facts and fiction is fiction, A lie doesn't just become the truth because it's on the front page of a newspaper," Pruitt said in both of his opening statements to the Energy and Commerce Committee's subpanel on environment and the Appropriations Committee's subpanel on the Interior Department and EPA.

2) If any lawmakers were expecting apologies or contrition from Pruitt, they were disappointed.

Pruitt shifted blame on his use of first-class travel, unauthorized staff raises and construction of a soundproof privacy booth to staffers, his security detail and oversight authorities.

For his frequent first-class traveling, Pruitt cited a memo from the Office of the Inspector General outlining threats against him.

"I was flying coach. I made changes after the threats," he said, adding that he has since asked his security detail to let him fly coach.

On the agency's decision to approve substantial raises to two EPA staffers who had moved to Washington, D.C. from Oklahoma with Pruitt -- one of whom he described at the earlier hearing as a "close friend" -- the chief said he was not aware of the type or amount of the raises. He admitted however that he was aware of the raises -- contradicting a previous statement he'd made to Fox News.

Pruitt also repeatedly claimed that he was not aware of the exorbitant, nearly $43,000 cost of a privacy booth installed in his office last year. He said he did not sign off on the booth and blamed "career staffers" for being involved "from the beginning to the end."

3) Republicans focused on Pruitt's spending.

GOP lawmakers raised concerns that the controversies could undercut Pruitt's work at the EPA.

"I am concerned that the good progress being made on the policy front is being undercut by the allegations about your management of the agency and use of its resources," said Rep. Greg Walden Gregory (Greg) Paul WaldenTrump order on drug prices faces long road to finish line Ignore the misinformation: The FDA will ensure the safety of any COVID-19 vaccine Hillicon Valley: Trump backs potential Microsoft, TikTok deal, sets September deadline | House Republicans request classified TikTok briefing | Facebook labels manipulated Pelosi video MORE (R-Ore.), chairman of Energy and Commerce. "These issues are too persistent to ignore."

They mostly focused on his allegedly exorbitant spending.

But Pruitt also received support from some GOP lawmakers, who saw him as the victim of unfair criticism.

"I apologize for the abrasiveness of some of my colleagues who would rather tarnish your character than really try to delve into the issues facing this great nation," said Rep. Jeff Duncan Jeffrey (Jeff) Darren DuncanGOP lawmaker calls for Confederate portrait to be put back in Capitol Rep.

Inside the hearing room: Protesting at Pruitt's hearings Thursday was relatively muted.

The biggest protest was when a group of attendees hoisted signs up behind Pruitt labeling him "Mr. Corruption."

Some attendees were also wearing bright green "Impeach Pruitt" shirts. They were also outside when Pruitt drove to the hearing, along with a giant papier mache head meant to look like Pruitt.

What's next: Pruitt's appearance was widely seen as a make-or-break moment for his tenure in Trump's Cabinet.

While Democrats and environmentalists saw the hearing as a disaster for Pruitt, Trump is unlikely to see it that way. He's stood steadfast behind Pruitt up until now, and there's no indication that will change.

That could provide another opportunity for Democrats to hit Pruitt over the same issues.

POLL FINDS MOST DISAPPROVE OF PRUITT: During the morning hearing, Quinnipiac University released a major poll, which included voters' approval of Pruitt.

Polltakers found that 52 percent of voters disapprove of his work at the EPA, compared with just 25 percent who approve.

Republicans were far more likely than Democrats to approve of Pruitt, at 51 percent to 7 percent.
