A video depicting a macabre scene of a fake President Trump shooting, stabbing and brutally assaulting members of the news media and his political opponents was shown at a conference for his supporters at his Miami resort last week, according to footage obtained by The New York Times.

Several of Mr. Trump’s top surrogates — including his son Donald Trump Jr., his former spokeswoman Sarah Huckabee Sanders and the governor of Florida, Ron DeSantis — were scheduled to speak at the three-day conference, which was held by a pro-Trump group, American Priority, at Trump National Doral Miami. Ms. Sanders and a person close Mr. Trump’s son said on Sunday that they did not see the video at the conference.

The video, which includes the logo for Mr. Trump’s 2020 re-election campaign, comprises a series of internet memes. The most violent clip shows Mr. Trump’s head superimposed on the body of a man opening fire inside the “Church of Fake News” on parishioners who have the faces of his critics or the logos of media organizations superimposed on their bodies.
