President Donald Trump faces the challenge of convincing Republican senators, global investors, voters and even Elon Musk that he won’t bury the federal government in debt with his multitrillion-dollar tax breaks package.

At a celebratory rally after Trump’s inauguration, Musk’s White House career got off to a contentious start when he seemingly offered a straight-arm salute at the Capitol One Arena in Washington, D.C., as he excitedly told the crowd: “My heart goes out to you.”

"It is very hard to separate Elon Musk's brand from the brand of Tesla, and SpaceX," a Harvard Business fellow told Newsweek.

Elon Musk has left the White House with little fanfare after splitting with Trump on policy and failing to meet his DOGE savings goals.

President Trump held a public farewell in the Oval Office on Friday for his close ally and DOGE mastermind Elon Musk. Meanwhile, the New York Times has new reporting about Musk's alleged drug use while on the campaign trail supporting Trump last year.
