Among the 3,000 people Hillary Clinton drew to a rally in Florida last night was the father of the man responsible for killing 49 people at the Pulse nightclub in Orlando on June 12, according to a local news report.
A Clinton campaign official tells NPR that the rally in Kissimmee, Fla., on Monday was open to the public. NBC affiliate WPTV identified one attendee as Seddique Mateen, the father of Omar Mateen, who was killed in a shootout with police after carrying out the deadliest mass shooting in modern U.S. history.
"This individual wasn't invited as a guest, and the campaign was unaware of his attendance until after the event," said the Clinton campaign official in an email exchange.
Not only was Mateen at the event, but he was positioned behind Clinton, so he was visible in photos and video of the candidate's speech. Mateen is recognizable, in part, because he did so many interviews after the nightclub attack.
