WASHINGTON — President Trump warned Saturday that his former ally Elon Musk will face “very serious consequences” if he starts bankrolling Democratic candidates for office, while adding that it’s “a shame that he’s so depressed and so heartbroken.”

“If he does, he’ll have to pay the consequences for that,” Trump told NBC News’ Kristen Welker in a phone interview Saturday.

“He’ll have to pay very serious consequences if he does that,” the president added, without specifying.

“Is there anything else you just want people to know about the status,” Welker asked.

“No, not at all. We’re doing great,” Trump replied. “The bill is great. It looks like we’re going to get it passed. Looks strongly like we’re going to get it passed.”

Trump said he was  “very confident” that the bill would get passed by July 4.

Musk knocked Trump during a multi-day X tirade over the debt increases contained in the “big beautiful bill” earlier this week and said without his hundreds of millions of dollars in contributions, the president would never have been re-elected in 2024.

He also claimed credit for delivering the GOP a 53-47 majority in the Senate and holding onto its majority in the House.

The Tesla and SpaceX billionaire contributed more than a quarter of a billion dollars to Republican candidates in the 2024 cycle, federal campaign filings show.

Musk departed the Trump administration two days before his 130-day term as a special government employee with the Department of Government Efficiency (DOGE) ended.

“I think, actually, Elon brought out the strengths of the bill because people that weren’t as focused started focusing on it, and they see how good it is,” Trump said in a rare point of praise for his former ally.

“So in that sense, there was a big favor. But I think Elon, really, I think it’s a shame that he’s so depressed and so heartbroken.”

On Thursday, the feud over the reconciliation bill got personal — with Trump threatening to cancel billions of dollars in government contracts and subsidies awarded to Musk’s companies.“I’d be allowed to do that,” he told Welker when asked about the threat, “but I have, I haven’t given it any thought.”

The world’s richest man returned fire and tweeted — but two days later deleted — that the president was blocking the release of files on the convicted pedophile Jeffrey Epstein because the information would implicate him.

Both Epstein’s former lawyer, David Schoen, and Trump have pointed out that the president’s association with the deceased financier in the 1990s — who was found dead in a New York City jail cell in August 2019 after being charged with sex trafficking — was a matter of public record.

“I was hired to lead Jeffrey Epstein’s defense as his criminal lawyer 9 days before he died,” Schoen posted on X Thursday. “He sought my advice for months before that. I can say authoritatively, unequivocally, and definitively that he had no information to hurt President Trump. I specifically asked him!”

“That’s called ‘old news,’ that’s been old news, that has been talked about for years,” Trump added Saturday.

The president banned Epstein from his Mar-a-Lago club over an incident with a club member’s teen daughter in 2007 — the year before the financier was convicted of soliciting sex from a minor.

Musk has also suggested that Trump should be impeached — but he’s since scrubbed his social media, too, according to Fox News.

Asked by Welker Saturday whether their relationship could be repaired, Trump said, “No.”

“I’m too busy doing other things,” he added, lashing out at the billionaire for being “disrespectful to the office of the President.”

“I have no intention of speaking to him,” Trump also said after Musk reportedly tried to de-escalate the situation in a phone call with the president Friday, which the White House rejected.

Republicans are currently deliberating the reconciliation bill in the Senate, with the House having already passed it.

The bill, which will be able to pass by a simple majority, includes a permanent extension of Trump’s 2017 tax cuts, hundreds of billions of dollars in additional border security and national defense funding and the revocation of green-energy tax credits passed under reconciliation by former President Joe Biden.

The measure is projected to increase the national deficit by nearly $3 trillion, according to the Congressional Budget Office, and Trump remains confident it will pass the Senate by July 4.

“The Republican Party has never been united like this before. It’s never been. It’s actually more so than it was three days ago,” he told Welker.

Musk had sought up to $1 trillion in spending cuts to the federal government but left the federal post after securing just around $175 billion.

Those cuts were not included in the GOP reconciliation bill.

Congressional Republicans and the White House remain confident that some of those savings will be codified as part of rescissions bills in the coming months — the first of which to cut federal funding for NPR and PBS was received in the House last week.

Musk contributed tens of thousands of dollars to House Democratic candidates as recently as 2018 and maxed out donations for the campaigns of Sens. Chris Coons of Delaware, Gary Peters of Michigan and Jeanne Shaheen of New Hampshire in 2020.
