Former President Donald Trump will reportedly blacklist anyone who works for Florida Governor Ron DeSantis as part of an effort to stop the governor from running for president.

The blacklist, which was first reported on by the right-of-center publication RealClearPolitics, will extend to anyone who has worked on tour to promote the governor’s new #1 bestselling book “The Courage to Be Free: Florida’s Blueprint for America’s Revival” or who works on a potential presidential campaign for the governor.

“It’s a time for choosing,” a source close to Trump told the publication. “If you work for Ron DeSantis’ presidential race, you will not work for the Trump campaign or in the Trump White House.”

If Trump were to win the presidency again he would have significant power over the national Republican Party and could try to enforce the same blacklist there.

A prominent conservative grassroots organizer, who spoke on the condition of anonymity, warned against Trump’s “loyalty test,” saying, “It’s the American people who will ultimately decide who is the next president and many grassroots see through these desperate pleas for allegiance and instead wish there was a substantive debate about the future of our great country.”

The report also cited a former senior administration official who said, “I don’t think, just knowing him, that it’s a serious assertion.”

“This is just being done now to try to kill the momentum that DeSantis has – this doesn’t jive with his past behavior,” the official added.

The news comes after Trump attacked DeSantis during a campaign rally in Texas over the weekend.

A lengthy clip flagged by Mediaite showed the former president’s attacks not landing well with the crowd, who grew mostly silent. “Compared to how Trump’s crowd normally reacts to his bits, the reaction to his mocking DeSantis was practically dead air,” the report said.

Trump attacked DeSantis’ response to the pandemic, said that DeSantis was “not good” on crime, and mocked him with nicknames. Trump’s attacks come as an analysis from Fox News this week found that Trump attacks DeSantis four times more than he attacks President Joe Biden.

“When a man comes to me with tears in his eyes, he’s had almost nothing in the polls,” Trump claimed while referencing DeSantis’ 2018 gubernatorial run. “He’s at almost nothing, he’s got no cash.”

“And I said, I can’t give you an endorsement. There’s no way you can when you’re dead,” Trump claimed. “I said, let’s give it a shot, Ron. I endorsed him. He became like a rocket ship. Within one day the race was over.”

Trump’s guests also attacked DeSantis at the rally, including Rep. Matt Gaetz (R-FL) and Mike Lindell.

Lindell called DeSantis “Trojan horse Ron DeSantis,” and then said that “the best thing he can do is endorse Donald Trump tomorrow morning.”

Trump attorney Christina Bobb also attacked DeSantis in Waco, saying that “if he actually does try to enter this race, [he] will come out a bloodied pulp.”

A conversation with President Joe Biden’s climate czar John Kerry took off when it turned to the use of private flights, a sore topic for jet-setting world leaders pushing the fight against global warming.

Ben Adler, senior climate editor at Yahoo News, broached the issue during an interview posted online on Friday, saying he read that Kerry “recently switched” from flying private to flying commercial.

“No, I didn’t fly private while I was in this job,” Kerry said, flatly rejecting the assertion. “It’s just a misnomer.”

"You recently switched, I read, from flying private to flying commercial…"

Kerry, who became the nation’s first special presidential envoy for climate at the start of the Biden administration, said he has had “one, maybe two private flights, which were military flights in order to get to China during COVID.”

“We were forced into that,” he insisted before adding, “I fly commercially.”

Fox News reported last month that Kerry’s family sold their private jet, a Gulfstream GIV-SP, to a New York based-hedge fund after it made headlines for how many trips it took and its estimated hundreds of metric tons of carbon dioxide emissions since the start of the Biden administration.

Adler also pressed Kerry to respond to critics who say there is hypocrisy in world leaders at the forefront of the climate agenda who also fly private jets to major climate events in places such as Davos.

“I’ve talked to them about it,” he replied, in reference to his contemporaries. “They offset — they buy offsets, they offset, and they are working harder than most people I know to be able to try to effect this transition.”

The Republican National Committee, which shared clips of the interview on Twitter, highlighted these remarks as Kerry defending “global elites” who fly private while advocating for climate action.

Carbon offsets are “tradable ‘rights’ or certificates linked to activities that lower the amount of carbon dioxide (CO2) in the atmosphere,” according to the Massachusetts Institute of Technology’s Climate Portal website. “By buying these certificates, a person or group can fund projects that fight climate change, instead of taking actions to lower their own carbon emissions. In this way, the certificates ‘offset’ the buyer’s CO2 emissions with an equal amount of CO2 reductions somewhere else.”

Kerry further argued that even as there is a push for climate-friendly changes, including the toward the increased use of what the Energy Department describes as low-carbon sustainable aviation fuels, people should be “thoughtful” about how impractical it would be to suddenly wipe out every aircraft in the world that relies on fossil fuels.

Kerry, the Democrats’ failed 2004 presidential nominee, previously served as U.S. senator and as secretary of state under former President Barack Obama. Kerry helped negotiate the Paris climate agreement and in 2019, when he faced criticism for his use of a private jet for a trip to Iceland to receive an award for climate leadership, defended himself by saying, “If you offset your carbon, it’s the only choice for somebody like me who is traveling the world to win this battle.”
