After Trump introduced Musk to the stage, the tech mogul enthusiastically jumped in the air several times while supporters cheered. 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.

Elon Musk appeared at Trump's recent rally in Butler, Pennsylvania, where he literally jumped for joy while coming on stage ("He's acting like a guy who won a radio contest," says Jon Stewart in the Daily Show clip above) before making a speech about the importance of the First and Second Amendments.

Elon Musk has praised Donald Trump as the only candidate “to preserve democracy in America." The SpaceX and Tesla CEO stood alongside the GOP nominee at a rally Saturday in Butler, Pennsylvania, where Trump had survived an assassination attempt in July.

Antonio Brown took to social media to call out NBC for "intentionally" not showing Elon Musk, who was at the Dallas Cowboys vs Pittsburgh Steelers game.
