Joe Biden is set to announce he will run for a second term as US president next week, according to US media.
Mr Biden’s advisers are planning to launch his re-election campaign as soon as next Tuesday, three sources said.
The 80-year-old president’s advisers have said for months that no formal timetable has been agreed for him to launch his campaign.
However they have long had their sights set on 25 April, the anniversary of Mr Biden’s 2020 campaign announcement, as an informal target.
Mr Biden will launch his candidacy for next year’s election with a campaign video message – just as he did four years ago, the sources said.
The timing and method of the announcement mirrors how the Obama-Biden ticket launched its re-election bid in 2011.
Jen O’Malley Dillon and Anita Dunn, senior White House advisers overseeing the announcement of Mr Biden’s campaign, both worked on Mr Obama’s re-election effort.
Advisers have cautioned that plans could still change based on a range of factors, with one source saying that nothing is official until the president announces it himself.
