President Donald Trump's threat to cancel Elon Musk's government contracts would have far-reaching implications, experts said.

Donald Trump threatened on Thursday to cut off government contracts to Elon Musk's companies and the world's richest man suggested the U.S. president should be impeached, marking a stark end to an unlikely alliance and leaving onlookers wondering what was next.

President Trump said his relationship with Elon Musk might be over after Musk spent the past few days trying to defeat Trump's "big, beautiful bill."

NASA entrusts SpaceX with the lives of its astronauts, and the Pentagon relies heavily on the company to launch its most sensitive satellites.

In the heat of the moment, Elon Musk threatened to decommission SpaceX’s Dragon spacecraft and then he took it back. In doing so, however, the rocket billionaire dragged NASA into his messy breakup with Donald Trump, with the agency’s access to orbit now at stake.
