Joe Biden newest information: Latest updates as Democrats again Kamala Harris

Donald Trump claimed that Joe Biden’s positive COVID test was phony, demanded he resign and issued an ultimatum to likely new opponent Kamala Harris.

Trump made a series of posts to his Truth Social account attempting to destroy the narrative around Biden’s decision, including the positive COVID-19 test that left the president at home the past few days.

The former president added that he believes Biden is ‘going to wake up and forget that he dropped out of the race today!’

A slew of Hollywood A-listers have backed Kamala Harris to take on Donald Trump for the presidency since she was endorsed by President Biden.

President Biden’s decision to drop out of the 2024 presidential race leaves Democrats scrambling to replace him with less than four months to go before Election Day.

What follows will be an unprecedented chain of events with Kamala Harris the favorite but by no means certain to become the party’s nominee.

The Democratic National Convention runs from August 19 to 22 in Chicago and Biden had been expected to formally accept the nomination there.

What are the nominating rules?

The Democratic party does have rules in place which determine what happens should the president step aside before being formally nominated.

While Biden had the necessary delegates his formal nomination was set to take place during a virtual roll call before the convention. The latest guidance is that it would happen in the first two weeks of August, but not before August 1.

Because Biden exited the race before officially becoming the nominee the more than 3,900 pledged delegates get to cast their ballots in an open convention for whichever candidate they want.

Every alternative to Biden whose name had been floated prior to him dropping out of the race insisted they were backing Biden. It’s not clear who would jump in the race aside from Harris with his departure.

If a candidate wins the majority of pledged delegates on the first ballot, they become the party nominee.

If no candidate gets a majority, then the nearly 740 so-called ‘superdelegates’, also known as automatic delegates, get to vote as well. They include a mix of party members and elected officials.

Voting continues until a candidate gets a majority of delegates.

The 81-year-old president was isolating with COVID at his $3.4 million holiday home in Delaware, when aides showed him data that convinced him he was no longer able to beat Donald Trump.
