Elon Musk has a "weird bitterness" about the Biden administration, Barry Diller told the "Fire and Fury" podcast.

The group chat — which is normally filled with memes — became fixated on Musk and his involvement with Trump’s campaign.

Musk, who wore a black Make America Great Again cap, warned in his speech that "this will be the last election" if the former president does not win in November while urging people to vote.
