Former US President Barack Obama will campaign for Democratic party presidential candidate Joe Biden in Pennsylvania next week, the Biden campaign has said.
Biden, 77, was the vice president during Obama's two terms.
While Obama has endorsed Biden and his running mate and India-origin Senator Kamala Harris by making online campaigns for them, this would be the first time that the 59-year-old former president would be campaigning in person.
Four years after he left the presidency, Obama because of his oratory skills, still remains the biggest crowd-puller for the opposition Democratic party.
"On Wednesday, October 21, (former) President Obama will travel to Philadelphia, Pennsylvania, to campaign on behalf of Joe Biden and Kamala Harris," the Biden campaign said in a statement on Friday afternoon.
No other details were immediately available.
Biden, as per the latest opinion polls, leads against Republican incumbent President Donald Trump by over nine points on an average.
However, there are signs that the polls are tightening, especially after Trump resumed his rallies after recovering from COVID19. He has been attracting thousands of supporters to his election rallies in the battleground states.
Obama is the only Democratic leader who can attract a big crowd in his election rallies. He's jumping into the campaign, with a little over a fortnight left for the presidential elections, is likely to motivate and encourage Black Americans and fence-sitters to come out and vote, Biden strategists believe.
A day earlier, the Democratic National Committee released a new ad featuring Obama, "The 2020 Election Is Already Here." It highlights the stakes of this election, the importance of Americans voting now to make their voices heard and how they can find all the information they need to make their plan to vote.
"Millions of Americans are already voting, make sure you stand up and join them," Obama said in the ad.
"There will always be reasons to think your vote doesn't matter -- that's not new. What is new is a growing movement for justice, equality and progress on so many issues. This really is a tipping point, and that momentum only continues if we win this election. But it's gonna be close. It could come down to a handful of voters just like you. So I'm asking you to bring this thing home. Leave no doubt. Vote early," he said.
The ad is being run in all the battleground States through digital platforms including Facebook, Instagram, Hulu, and YouTube.
During the Democratic National Convention this summer, Obama had launched a blistering attack against Trump. "Donald Trump hasn't grown into the job because he can't," he said in August.
"And the consequences of that failure are severe. 170,000 Americans dead. Millions of jobs gone while those at the top take in more than ever. Our worst impulses unleashed, our proud reputation around the world badly diminished, and our democratic institutions threatened like never before," Obama said.
