US President Barack Obama and the woman who wants to succeed him will make their first campaign appearance together next week.
Mr Obama and Democrat Hillary Clinton, who was his Secretary of State, will campaign together on Tuesday in Charlotte, North Carolina – a swing state that Mr Obama won in 2008 but lost in 2012.
Democrats dearly want to take North Carolina in the November election, when Mrs Clinton is likely to run against Republican Donald Trump.
Mrs Clinton’s campaign said she and the current president will discuss their vision “for an American that is stronger together”.
Meanwhile, Democrat Bernie Sanders, who has not yet abandoned his presidential campaign, has said Mr Trump “could benefit from the same forces” that led Britain to vote to leave the European Union.
Writing in the New York Times, he said any political advantage flowing to Mr Trump from the vote “should sound an alarm for the Democratic Party”.
He said American voters, like those in the UK who supported Brexit, “are understandably angry and frustrated by the economic forces that are destroying the middle class”.
