Former US Presidents Barack Obama and Bill Clinton have joined incumbent Joe Biden in the election campaign. The three Democrats appeared together at a major fundraising event in New York that raised more than $26 million, according to Biden's campaign.
Republican former President Donald Trump, who wants to run against Biden again in the presidential election in November, was also in the city. The election campaign show was accompanied by criticism of the US government's Middle East policy. Protesters interrupted the prominent Democrats on stage several times with heckles. Others demonstrated outside.
