Sen. Elizabeth Warren is asking Secretary of State Marco Rubio for information on the Trump administration’s contingency plans if billionaire Elon Musk breaches his companies’ current contracts with the U.S. amid the ongoing public fall out between him and President Trump.
In a letter to Rubio as acting national security adviser and obtained by CBS News, Warren said Mr. Trump and Musk’s public disagreements about the upcoming reconciliation bill that escalated into a public online spat could “have serious implications for U.S. national security.”
The Massachusetts Democrat mentioned Mr. Trump’s proposal to terminate Musk’s government contracts and subsidies, which the world’s richest man followed with a threat that SpaceX would “begin decommissioning its Dragon spacecraft immediately.” Musk has since walked back his threat.
“No petty social media fight between the president and a billionaire should jeopardize U.S. national security,” Warren said.
In addition to contingency plans for SpaceX, the senator asked for information regarding the impact on U.S. agencies’ satellite communications if Musk’s Starlink is turned off. Additionally, she asked Rubio to provide any analysis that the Trump administration has conducted “of its authorities and options under the Defense Production Act to address vendor lock, monopolies, or contractor refusal to meet national security needs.”
She asked to receive answers to her questions by June 14, whether through a classified briefing or preferably a public response that can be released to Congress and the public, the letter said.
Warren has been a vocal opponent of Musk and his involvement in the Trump administration. Last week, she released a report that outlines instances her office has found of Musk benefiting from it.
Musk’s rocket company has received tens of billions of dollars from the federal government over the last decade, including $3.8 billion in the 2024 fiscal year alone, according to federal records.
The bulk of those federal grants are from NASA, which has paid SpaceX billions over the last decade to ferry astronauts and supplies to and from the International Space Station. The agency has also awarded SpaceX upwards of $2 billion in recent years to design and build a lunar lander, as part of NASA’s Artemis program, which aims to return humans to the moon for the first time in a half-century.
While the public spat appears to have cooled somewhat, Mr. Trump told NBC News’ Kristen Welker in a phone interview on Saturday that he has no plans to make up with the mega-billionaire.
“I’m too busy doing other things,” Trump continued. “You know, I won an election in a landslide. I gave him a lot of breaks, long before this happened, I gave him breaks in my first administration, and saved his life in my first administration, I have no intention of speaking to him.”
When asked by a reporter Friday if he’s still considering rolling back subsidies to Musk as a money-saving move, Mr. Trump suggested he was open to it.
“He’s got a lot of money, he gets a lot of subsidy. So we’ll take a look at that,” the president said on Air Force One. “Only if it’s fair for him and for the country. I would certainly think about it, but it has to be fair.”
This isn’t the first time the president has needled Musk over his companies’ federal subsidies. In a 2022 feud, Mr. Trump claimed Musk would be “worthless” without hefty subsidies for “electric cars that don’t drive long enough” and “rocketships to nowhere.”
The two mended their relationship then and Musk spent hundreds of millions to help elect Mr. Trump in 2024. The billionaire went on to lead the Trump White House’s cost-cutting Department of Government Efficiency until last week.
