After his break with the Trump White House, Musk says he's starting the America Party. Cuban seems interested in the idea.

Already, he’s receiving support from others in his tax bracket, including Mark Cuban. The billionaire businessman reposted Musk’s announcement with a fire emoji, and later followed up with: “I work with the Center for Competitive Democracy. They will help you get on ballots. That is their mission.”

Billionaire EV king Elon Musk's new political party has drawn interest from fellow fat cats Mark Cuban and Anthony Scaramucci.
