Following the attempted assassination on Saturday, billionaire businessman Elon Musk and hedge fund manager Bill Ackman officially endorsed Donald Trump for president in the approaching U.S. election.

Following the shooting, Elon Musk, the CEO of several companies, including the electric vehicle manufacturer Tesla and the rocket manufacturer SpaceX, posted a flurry of remarks on his social media site X. These remarks included criticism of the Secret Service and support for the former president.

“I fully endorse President Trump and hope for his rapid recovery,” Musk wrote in one post, attaching a video of Trump being whisked off stage following the attempt. In a subsequent post he said, “Last time America had a candidate this tough was Theodore Roosevelt.”

The two endorsements are victories for Trump since they include individuals with enormous financial and social media influence as well as commercial acumen.

Musk had previously expressed his discontent with Democratic President Biden and has grown closer to Republican President Trump in recent months. However, the remarks he made on Saturday were his clearest public endorsement of Trump’s campaign for reelection. Additionally, he said, “You’re right,” in response to a user’s remark suggesting that Trump should select U.S. Sen. JD Vance (R., Ohio), for vice president.
