US election campaign live: Donald Trump warns there will be 'bedlam' during vote count

President Donald Trump has warned the already contentious US election will descend into chaos if the vote count proceeds as planned.

Welcome to our live coverage of the US presidential election campaign.

Both candidates kept themselves busy today. President Donald Trump held four rallies in the crucial swing state Pennsylvania. Joe Biden was in Michigan, where he was appearing at a couple of events alongside his former boss, Barack Obama. And the two vice presidential nominees, Mike Pence and Kamala Harris, were crisscrossing the country as well.

"We're spending the day in Pennsylvania, and I think we're doing extremely well with the votes," Mr Trump told reporters as he left the White House this morning.

"It's going to be a very interesting three days. It's going to be a very interesting Tuesday.

"A big, red wave has formed. We're doing very well."

Red, of course, is the colour associated with Mr Trump's Republican Party.

Once he got to Pennsylvania, the President repeated most of his usual lines, but he focused in on a relatively fresh complaint about the fact that the vote count will continue after election night.

Recent rulings from the Supreme Court mean a handful of key swing states, including Pennsylvania, will accept mail votes that arrive after election day (the exact cut-off date varies depending on the state), as long as they are postmarked by election day.

"This is a terrible thing that they have done to our country. And that's the United States Supreme Court I'm talking about. That is a terrible, political, horrible decision that they made," said Mr Trump.

"We're going to be waiting. November 3rd is going to come and go and we're not going to know. And you're going to have bedlam in our country."

To be clear, there is nothing remotely unusual about the vote count proceeding for days, and even weeks, after election night. It happens in every election, the idea being that every vote cast should, you know, actually be counted.

The states have until December 8 to certify and report their results.
