The White House on Friday lashed out at for promoting " and racist hate" after the CEO and X Corp. owner said he agreed with a post accusing "Jewish communities" of pushing "hatred against whites."
Musk, on X, wrote that that post "said the actual truth."
White House spokesman Andrew Bates said it was "unacceptable to repeat the hideous lie behind the most fatal act of Antisemitism in American history at any time."
Bates appeared to be referring to the at the Tree of Life Synagogue in Pittsburgh in 2018, in which 11 people were shot to death by a gunman who expressed a belief in the antisemitic " " conspiracy theory.
"We condemn this abhorrent promotion of Antisemitic and racist hate in the strongest terms, which runs against our core values as Americans," Bates said.
The White House's statement noted the proximity of Musk's post to the deadly attacks in Israel by Hamas on Oct. 7, which it described as "the deadliest day for the Jewish people since the Holocaust."
"We all have a responsibility to bring people together against hate, and an obligation to speak out against anyone who attacks the dignity of their fellow Americans and compromises the safety of our communities," Bates said.
Spokespeople for Tesla and X did not immediately respond to CNBC's requests for comment on the White House's statement.
Musk on Wednesday responded to a post claiming Jewish communities "have been pushing the exact kind of dialectical hatred against whites that they claim to want people to stop using against them."

In a 2018 on the platform formerly known as Twitter, he wrote, "Who do you think *owns* the press? Hello." After that tweet spurred accusations of antisemitism, Musk blamed a Twitter "glitch" for hiding another post in the thread and "removing context" that clarified he was referring only to "powerful people."
