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.

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.

Musk also claimed liberal states were "making crime legal" during an interview with Tucker Carlson.
