Obama will travel to Philadelphia, Pennsylvania, on Wednesday to campaign on behalf of Biden and Democratic vice presidential nominee Kamala Harris, the campaign said in a statement.
It did not provide any further information about the event and said additional details would follow.
The 59-year-old Obama remained on the sidelines during the Democratic presidential primaries but endorsed his former deputy after he won the party nomination.
Obama said the 77-year-old Biden “made me a better president.
“He’s got the character and the experience to make us a better country,” he said.
