U.S. President Joe Biden believes that Elon Musk's relationship with other countries deserves attention, Reuters reports.

At a press conference, Biden was asked whether he considers Musk a threat to national security and whether the U.S. government should investigate his acquisition of Twitter with the help of the Saudi conglomerate. “I think that Elon Musk’s cooperation and/or technical relationships with other countries is worthy of being looked at,” Biden said. “Whether he is doing anything inappropriate, I’m not suggesting that. I’m suggesting they’re worth being looked at.”

Last month, the White House said reports that the United States was discussing launching a national security review of some of Musk's businesses, including Twitter, were "not true."
