Kamala Harris and Donald Trump shared a handshake as they reunited after Tuesday night’s presidential debate at 9/11 memorial ceremony. The pair made a rare joint appearance with Joe Biden at the New York City site that marks the September 11 plane attacks in 2001 that killed nearly 3,000 people. Ms Harris, the Democratic presidential nominee and Mr Trump, her Republican rival in the November election, shook hands and exchanged a few words, despite their contentious debate the night before. Mr Trump’s running mate, Senator JD Vance of Ohio, also attended.
