NEW YORK (Reuters) -President Joe Biden, Vice President Kamala Harris and former President Donald Trump made a rare joint appearance on Wednesday at the New York City site that marks the Sept. 11 plane attacks in 2001 that killed nearly 3,000 people.

Harris, the Democratic presidential candidate and Trump, her Republican rival in the Nov. 5 U.S. presidential election, shook hands and exchanged a few words despite their contentious debate the night before, then lined up for the commemoration. Trump's running mate, Senator JD Vance, also attended.
