I'd imagine that the NSA is already aware of any incoming calls from Putin to an American citizen who has security clearances. The article also states that US officials are aware of the conversations. Does that mean Elon informed them, or is it due to surveillance? Who knows. The question is moreso....was Elon dumb enough to say certain shyt on the phone? The article also claims that Putin asked him to shut off Starlink in Taiwan, as a favor to Xi. If Putin is that comfortable to ask such a wild question - while presumably knowing he's being recorded - it opens up a lot of questions.
Given Elon's racism, antisemitism, unhinged behavior and his weird Trump support I'd hope that the government shytcans all contracts with him after the election is over.
