The Secret Service has launched a probe into an X post by Elon Musk in which he tweeted that “no one is even trying” to kill Kamala Harris or Joe Biden. The tech billionaire deleted the post on his X platform and passed it off as a “joke.” However, the White House did not find it funny and instead called it “irresponsible.”

The Secret Service told the BBC it’s “aware” of Musk’s post, adding, “As a matter of practice we do not comment on matters involving protective intelligence,” the statement added. “We can say, however, that the Secret Service investigates all threats related to our protectees.”

The US Secret Service says it is "aware" of a social media post by Elon Musk in which he said that "no one is even trying" to assassinate President Joe Biden or Vice-president Kamala Harris. Mr Musk has since deleted the post and said it was intended as a joke.
