Update:

White House spokeswoman Stephanie Grisham tweeted Monday that President Donald Trump "strongly condemns" the video that was reportedly played during a conference of his supporters last week at the Trump National Doral Golf Resort in Miami.

Grisham said Trump "has not yet seen the video" but denounced it "based upon everything he has heard."

Re: the video played over the weekend: The @POTUS @realDonaldTrump has not yet seen the video, he will see it shortly, but based upon everything he has heard, he strongly condemns this video. — Stephanie Grisham (@PressSec) October 14, 2019

Judd Legum, author of the Popular Information newsletter, called Grisham's statement "a joke."

"If he wanted to condemn it, he could," Legum tweeted. "He's not. Instead, he has his press secretary release a perfunctory statement. The entire thing is a wink and nod to his supporters."

Earlier:

An edited video depicting President Donald Trump gunning down his political opponents and the media inside a church was reportedly played to a conference of his supporters last week at the Trump National Doral Golf Resort in Miami, drawing outrage from journalists and others who condemned the clip as blatant incitement to violence.

The New York Times, which obtained footage of the clip being shown at the pro-Trump conference, reported late Sunday that the video "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."

"The video of a mass shooting by the president inside a church is reminiscent of the Charleston shooting. Executing members of the media is reminiscent of the Maryland newsroom shooting."

The video is an edited scene from the 2014 film "Kingsman: The Secret Service" and contains a logo for Trump's 2020 reelection campaign.

Among those targeted in the video are Sen. Bernie Sanders (I-Vt.), former President Barack Obama, former Secretary of State Hillary Clinton, Black Lives Matter, Politico, and CNN.

The president's son Donald Trump Jr. and former White House press secretary Sarah Huckabee Sanders told the Times they did not see the video played at the conference.

Watch the video, which apparently originated from the right-wing account "TheGeekzTeam":

This video making the rounds that was shown at mar-a-lago of Trump killing all his critics is so evil and irresponsible, not to mention immature, it’s truly beyond words. Obama, McCain, Blake lives matter, the media..nobody is safe from these monsters. pic.twitter.com/N0NkdW85bi — Justin Kanew (@Kanew) October 14, 2019

Shannon Watts, founder of Moms Demand Action, said "the video of a mass shooting by the president inside a church is reminiscent of the Charleston shooting. Executing members of the media is reminiscent of the Maryland newsroom shooting."

"This video is racist and hateful," said Watts, "and it's flabbergasting that it was shown at Trump's resort."

In a statement, CNN said "this is not the first time that supporters of the president have promoted violence against the media in a video they apparently find entertaining—but it is far and away the worst."

"The images depicted are vile and horrific," said CNN. "The president and his family, the White House, and the Trump campaign need to denounce it immediately in the strongest possible terms. Anything less equates to a tacit endorsement of violence and should not be tolerated by anyone."

Jonathan Karl, president of the White House Correspondents Association (WHCA), called the video "vile and dangerous."

"All Americans should condemn this depiction of violence directed toward journalists and the president's political opponents," Karl said in a statement late Sunday. "We have previously told the president his rhetoric could incite violence. Now we call on him and everybody associated with this conference to denounce this video and affirm that violence has no place in our society."
