They've been there and done that and now they're disappointed with the work of their successors.

Three former Republican heads of the Environmental Protection Agency told ABC News on Tuesday that the current EPA under the Trump administration deserves a D grade, or maybe "a little lower" for its work. Christine Whitman, William Reilly, and Lee Thomas, who led the agency under former Presidents George W. Bush, George H.W. Bush, and Ronald Reagan, respectively, all agreed that the EPA's current leadership is supporting the "undermining of science" and taking a potentially "catastrophic" approach to climate change. They all also said they were concerned that the U.S. is heading toward undoing its recent gains in cleaner air and water.

"You need an agency that is credible, has consistency in its rule making, and is science-based," Thomas said, adding that he believes his old boss, Reagan, would want the agency to recommit to its original purpose.

Whitman and Reilly also both expressed excitement about the Green New Deal — at least in the sense that it has helped bring environmental policy to the forefront of the current political discourse.

The trio were in Washington to testify before a House Energy and Commerce subcommittee hearing on Tuesday, where they were also joined by another former EPA chief, Gina McCarthy, who led the agency under former President Barack Obama. Read more at ABC News. Tim O'Donnell

As the saying goes, "it's not a party until the bagpipes come out."

Attorney General William Barr got the party started on Wednesday morning, opening the U.S. Attorneys National Conference in Washington, D.C. with an inspiring bagpipe performance.

Barr dramatically emerged from backstage and received a standing ovation when U.S. Attorneys in attendance realized they'd be treated to a surprise performance from the nation's top law enforcement officer. But Barr is a longtime bagpipe aficionado. Before becoming attorney general in former President George H.W. Bush's administration, Barr performed in the City of Washington Pipe Band, one of the world's top bagpipe ensembles, reports The New Yorker. His fellow band member even went so far as to call Barr a "serious piper."

While he no longer competes, or plays daily as he once did, Barr reportedly keeps the party going with raucous bashes replete with fiddles, whiskey, and of course, bagpipes. Watch his Wednesday performance below, via Fox News. Summer Meza

Fox's Tomi Lahren has apparently had enough with all this talk of a humanitarian crisis at the southern border.

In a Wednesday appearance on Fox & Friends, Lahren was asked by guest host Jedediah Bila about comments from Rep. Alexandria Ocasio-Cortez (D-N.Y.) in which the congresswoman praised Wayfair employees for planning a walkout on Wednesday over the company's decision to sell beds to furnish migrant detention facilities. Bila questioned the logic of Ocasio-Cortez's opinions on the humanitarian border crisis, asking if she would rather the children in the facilities not have beds.

But while Bila appeared to agree that the situation at the border is a humanitarian crisis, Lahren dismissed that idea entirely, even putting the words in scare quotes. Instead, Lahren suggested, it's all a part of plan. Democrats like Ocasio-Cortez want to release currently-detained migrants into the "shadows of society" to overwhelm U.S. cities and become Democratic voters, turning red states blue.

"This is all strategy," Lahren said. "And they cloak it in a humanitarian crisis. It's an opportunity." Watch the clip below. Tim O'Donnell

President Trump in a Wednesday interview went on a bizarre rant about supposed Twitter censorship, claiming the company is intentionally making it difficult for people to "join" him.

During an interview with Fox Business' Maria Bartiromo that lasted nearly an hour, Trump bemoaned "what they did to me on Twitter," claiming it's "very hard for people to join me" and that the fact that he isn't picking up followers at as quick a rate as he used to is evidence of some sort of a conspiracy.

"I was picking up 100,000 followers every few days … then all of a sudden, it stopped," Trump complained.

Trump then bizarrely suggested that many of his supporters are unable to follow him on Twitter, adding a new item to his long list of things he claims people just keep walking up to him and saying.

"I've had so many people come to me [and say], 'Sir, I can’t join you on Twitter,'" Trump said. "I see what's happening 100 percent."

Trump had previously met with Twitter CEO Jack Dorsey in the Oval Office during a meeting that he supposedly spent "a significant portion of" complaining about losing followers and probably launching into a rant not dissimilar to this one, no doubt making Dorsey long to be back on one of his silent meditation retreats.

Special Counsel Robert Mueller spent two years heading up a major investigation into 2016 Russian election interference, but, come on, that doesn't mean he actually knows its details, says Fox & Friends host Brian Kilmeade.

The Fox & Friends team on Wednesday was discussing the news that Mueller is scheduled to testify before the House Intelligence and Judiciary committees on July 17. The Democrats, like House Judiciary Chair Jerrold Nadler (D-N.Y.), who have been pushing for Mueller's testimony for quite some time are undoubtedly excited by the news. But Kilmeade thinks it could actually backfire.

"He's like the King of England on this," Kilmeade said, referring to Mueller. "He assigns the people." Kilmeade added that Nadler-led hearings "often get out of control," and he senses this one might as well, with the results differing from the Democrats intentions.

Kilmeade did concede that Mueller has a few weeks to "bone up" on the report, and guest host Jedediah Bila said that if Mueller doesn't know the details now, she's pretty sure "he's sitting with a highlighter going over it" because he'll want to "make this his moment."

President Trump during a lengthy interview with Fox Business' Maria Bartiromo on Wednesday tore into Federal Reserve Chairman Jerome Powell, who he again said he has the right to fire.

Trump during the interview mocked Powell as a guy who "nobody ever heard of " before, saying that "I made him and now he wants to show how tough he is." This came after Bartiromo pointed out that Powell has said he won't be pushed around amid Trump's repeated criticism.

"Let him show how tough he is," Trump said of Powell. "He's not doing a good job."

The president also once again contended that he could fire or demote Powell while noting that he never said he's actually going to do so. After Bloomberg reported that Trump had discussed demoting Powell earlier this year, Trump said in a Sunday interview that he "didn’t ever threaten to demote him" but "I'd be able to do that if I wanted."

"We have a Fed that keeps raising interest rates," Trump also said on Wednesday. "I mean, you explain that one." Brendan Morrow

On Tuesday, Russell Moore, a prominent evangelical Christian theologian and president of the Southern Baptist Convention's Ethics and Religious Liberty Commission, deplored how the U.S. is treating detained migrant children, suggesting that "we can do better than this."

Jerry Fallwell Jr., a prominent evangelical leader who heads Liberty University and is famously friendly with President Trump, decided to publicly disagree, calling Moore "a bureaucrat" who has never "made a payroll" or "built an organization of any type from scratch."

The comments on Falwell's tweet veered from the saucy — "Have you ever hired a pool boy?" asked conservative pundit Bill Kristol. "Have naked photos of your wife ever showed up on Michael Cohen's computer?" — to the serious. "How did Jesus treat children?" asked Christian journalist Elizabeth Bruenig. Brian Zahnd, founding pastor of Missouri's Word of Life Church, brought the fire and brimstone:

Were there memes? Yes, there were memes.

Did anyone defend Falwell's thoughts on Christianity? If so, their comments were buried among questions about Jesus making payroll and how many people Falwell had just driven away from Christianity. To be fair, Falwell has pointed out that he is not an ordained minister, just a businessman who runs a Christian university. Maybe he can audit some New Testament classes this fall. Peter Weber
