The U.S. Secret Service has acknowledged being “aware” of a now-deleted X (formerly Twitter) post made by Elon Musk that mentioned assassination attempts on President Joe Biden and Vice President Kamala Harris.

Musk initially resisted calls to delete or reword the post, before ultimately taking it down. He later said the post was a joke.

Virtually everyone on Capitol Hill agrees that the Secret Service needs to do a better job. But Democrats and Republicans are at odds over whether to increase the agency’s budget.
