Tesla CEO Elon Musk swiped at a senior White House official late Wednesday following reports of a rift between the two men. 

Musk replied to a post on X, the social media platform he owns, linking to a New York Post story detailing that Sergio Gor had not submitted full vetting paperwork. Gor is one of the most influential officials in the White House, serving as head of the Office of Presidential Personal.

“He’s a snake,” Musk wrote of Gor.

Gor did not immediately respond to a request for comment.

Gor is a highly influential aide with strong ties to the MAGA movement. He is a close ally of Donald Trump Jr. and a fierce loyalist to the president. He also led the pro-Trump super PAC Right for America.

As head of the Office of Presidential Personnel, Gor oversees the vetting and appointments of thousands of government workers, ensuring they are aligned with Trump’s agenda.

Gor has been in the headlines as a central figure in the acrimonious split between the president and Musk, who departed his role as a special government employee late last month.

Musk and Gor reportedly clashed in recent months, including at Cabinet meetings where Musk chastised Gor over personnel disagreements. Gor was also cited as a key figure in pushing for the withdrawal of Jared Isaacman, a Musk ally who had been tapped to lead NASA. Trump pulled the nomination shortly after Musk’s departure from government, citing “prior associations,” a reference to Isaacman’s donations to Democrats.

An administration official told The Hill that the decision to pull Isaacman’s nomination ultimately rested with the president. The official also downplayed talk of a wider feud between Gor and Musk. They noted Gor oversaw the hiring of DOGE officials and argued the two were broadly aligned on the agency’s goals.
