The White House denounced Elon Musk on Friday for spreading a “hideous” antisemitic lie on his social media platform X this week, saying it was an “outrageous promotion of antisemitic and racist hate” that “violates our fundamental values as Americans.”

The White House statement came after at least two more big companies withdrew their ads from X following a report by Media Matters that revealed ads by IBM, Apple and others were shown next to content glorifying Adolf Hitler and the Nazi Party.

The White House criticized what it called an “outrageous promotion of antisemitic and racist hate” that “violates our fundamental values as Americans” in response to Musk’s post on Wednesday.

Musk on Wednesday supported a post on X that falsely alleged Jewish people were fueling hatred against white people, saying the user who mentioned the “Great Replacement” conspiracy theory was telling “the actual truth.”

That conspiracy theory claims that Jewish people and leftists are orchestrating the ethnic and cultural substitution of white people with non-white migrants that will result in a “white genocide.”

“Repeating the hideous lie … one month after the worst day for the Jewish people since the Holocaust is unacceptable,” White House spokesperson Andrew Bates said, referring to the October 7 attack on Israel by Hamas.

Musk and X’s representatives did not respond to requests for comment on Musk’s post on Wednesday.

Lions Gate Entertainment Corp announced yesterday that it was stopping its X ads, while Axios said Apple, the world’s biggest company by market value, was also suspending its ads. IBM IBM.N pulled its advertising from the platform on Thursday.

“On this platform — X has been very clear about our efforts to fight antisemitism and discrimination. It has no place anywhere in the world — it’s disgusting and wrong. Period,” X CEO Linda Yaccarino wrote on Thursday.

Advertisers have left the site since Musk acquired it in October 2022 and lowered content moderation, leading to a sharp increase in hate speech on X, civil rights groups have reported.

Antisemitism has been growing in recent years in the United States and globally. After the war between Israel and Palestinian Islamist group Hamas broke out following last month’s attack, antisemitic incidents in the United States surged by nearly 400 per cent from the same period last year, according to the Anti-Defamation League, a nonprofit that combats antisemitism.

Musk, chief executive of electric vehicle maker Tesla and founder of rocket company SpaceX, has accused the Anti-Defamation League of causing the ongoing decline in advertisers without providing any proof.
