Just days after buying Twitter, Elon Musk fuels a surge in misinformation on the service about the Pelosi attack

Within hours of the attack on Paul Pelosi, conspiracy theories deflecting blame for the assault on the husband of U.S. Speaker Nancy Pelosi were already swirling online.

It didn't matter that authorities said Paul Pelosi was alone when the suspect broke into the couple's San Francisco home. Or that investigators said they didn't believe the two men knew one another.

It didn't even matter that the suspect, David DePape, confessed to investigators that he broke into the Pelosi home to target the speaker.

Misleading claims about the assault spread rapidly anyway, and not just thanks to trolls in obscure internet chatrooms. The claims received a major boost from some prominent Republicans and Elon Musk, now the owner of Twitter, one of the world's leading online platforms.

On Monday, posts falsely suggesting a personal relationship between Pelosi and the alleged assailant, soared on Twitter, a day after Musk tweeted and deleted a link to an article suggesting one.

Musk hasn’t said why he linked to the article, or why he deleted his post, which came in response to a tweet from Hillary Clinton that condemned the attack. Twitter did not immediately respond to questions from The Associated Press on Monday.

“It’s like he forgot for a second that he was now the owner of the platform, and not just anther user who can say whatever he wants,” said Brad Greenspan, a tech entrepreneur and an early investor in MySpace. “Now, being the owner, there are a whole new set of responsibilities.”

One of several Republicans to amplify the baseless conspiracy theory, Rep. Marjorie Taylor Greene, R-Ga., defended Musk on Monday with a tweet that repeated the misleading claim about “Paul Pelosi's friend attacking him with a hammer.”

Rep. Clay Higgins, R-La., joked about the attack with his own tweet, since deleted, that repeated the conspiracy theory.

Donald Trump Jr., meanwhile, ridiculed Paul Pelosi on Twitter with false assertions.

The claim also spread to other platforms, including fringe sites like Gab and Truth Social, where posts mocked the 82-year-old victim.

San Francisco District Attorney Brooke Jenkins on Monday begged other political leaders to be mindful of their comments about the case.

“We of course do not want distorted facts floating around, certainly not in a manner that is further traumatizing a family that has been traumatized enough,” she said.

The posts focusing on Paul Pelosi were just a subset of a recent wave of hateful and conspiracy theory-laden posts that followed Musk's purchase of Twitter.
