Donald Trump and Elon Musk bromance timeline: Pair appear together at US election campaign rally [Video]

At one of Mr Trump’s election campaign rallies on Saturday (October 5), Mr Musk leaped around on stage in favour of the candidate.

During the appearance with Mr Trump, the tech entrepreneur painted a bleak picture of the impending presidential election, describing the Republican nominee as the only one “to preserve democracy in America”.

At the event, which took place at Butler, Pennsylvania, where the former president escaped an assassination attempt in July, Mr Musk wore a black-on-black cap with the campaign’s “Make America Great Again” patch on it and claimed that “this will be the last election” if Mr Trump lost.

The rally signified the two men’s developing alliance in the closing stages of the presidential race. Here’s how they got to this position.
