So, this is a very interesting point, legally. Was this journalism or was it a free campaign rally for Trump? If (as things appear) this was Elon Musk trying to help elect Donald Trump, then the Trump campaign has to treat the event as a campaign campaign contribution "in kind."

I read yesterday that public interest groups are already preparing complaints to certain federal agencies, claiming the interview was a campaign event that the Trump campaign has not paid for, in violation of election law.

I'm not a lawyer, and I don't know if the issue is all that legally clear — But I'll say one thing. What I listened to sounded like a campaign rally, not like journalism. At least insofar as any of it was coherent, which is you quite rightfully point out, much of it was not.
