US President Donald Trump announced on Friday that he will formally launch his 2020 re-election campaign on 18 June in Orlando, Florida.

In a tweet, Trump said he would hold a rally with his wife, Melania, Vice President Mike Pence and Mr Pence's wife Karen at 8 pm at the 20,000-seat Amway Center in Orlando, Florida.

Trump has already been raising money for his re-election and holding political rallies for many months.

But the official roll-out for his campaign for the 2020 presidential election will take place around the four-year anniversary of the day in 2016 when announced his candidacy at Trump Tower, New York City.

Mr Trump, who considers Florida to be something of a second home, won the state in 2016.

But as is the case for the president in many battleground states, his victory is not assured there in 2020, and he will likely face a fight to win it again.

The Trump campaign has privately expressed concern about Pennsylvania, Michigan and Wisconsin, the trio of upper Midwest swing states that provided his 2016 margin of victory.

Since Mr Trump took over as president in early 2017, unemployment has remained low and the US economy has kept growing. Typically, when the economy is vibrant, presidents would be strong bets for re-election.

But Mr Trump’s polarising presidency has given Democrats hope that one of them can deny him a second term. Republican strategists see Democratic front-runner Joe Biden posing a problem for the president in the Midwestern swing states.
