A hot mic captured Donald Trump being challenged by a member of the public as he attended the 9/11 memorial service in New York City on Wednesday. One of the attendees was picked up by C-SPAN’s microphones calling out the former president over his failure to show up in previous years. “Where were you for 20 years? I’ve been here. Where were you?” the angry person appeared to shout at Mr Trump. The Republican presidential candidate, who was standing next to running mate JD Vance, also shook hands with rival Kamala Harris after their contentious debate the night before.
