WASHINGTON — President Trump shared on Twitter a cartoon on Tuesday morning of a train running over a person with a CNN logo covering the person’s head, three days after a fatal collision in Charlottesville, Va. Trump deleted his retweet minutes later.

Trump has been under fire for how he has publicly addressed bloody demonstrations by white nationalists over the weekend. Promoting a cartoon of a person being run over by a train appeared to belittle the attack by a driver who ran into a crowd of counterprotesters, leaving a 32-year-old woman dead on Saturday and 19 others injured. An Ohio man has been charged with second-degree murder in the crash.

A White House official said early Tuesday that the tweet of the train was posted inadvertently and was deleted as soon as it was noticed.

A retweet requires two actions, clicks, or taps on a smartphone or computer, in order to post, meaning the president would have had a second chance to be sure he wanted to tweet the cartoon.

The president has long appeared to sanction violence, going back to his campaign when, at a rally, he said he wanted to punch a Black Lives Matter protester in the face. He later said the man, who was assaulted by Trump supporters in the crowd, might have deserved to get roughed up.

Trump and his associates have long been critical of CNN. On Tuesday, the president’s reelection committee issued a statement criticizing CNN for what the committee described as censorship because the news network did not air an advertisement released Sunday.

The ad briefly shows faces of television journalists, including several from CNN, with the words “attacking our president,’’ and a voice-over at the end says “the president’s enemies’’ as their faces reappear.

A network spokeswoman said CNN would have accepted the ad if the reporters and anchors had been removed.

“Anchors and reporters don’t have ‘enemies,’ as the ad states, but they do hold those in power accountable across the political spectrum and aggressively challenge false and misleading statements and investigate wrongdoing,’’ Barbara Levin, the spokeswoman, said.

In July, Trump posted a video on his Twitter account portraying him wrestling and punching a figure whose head had been replaced by the CNN logo. The video appeared to be an edited clip from years ago when Trump was part of a professional wrestling event.

In a speech on Long Island, New York, a few weeks ago, the president told a group of law enforcement officers assembled for the event that he preferred they not be too “nice’’ with criminal suspects, a remark that drew widespread condemnation.

President seems to retweet insulting message

WASHINGTON — President Trump appears to have mistakenly retweeted a message from one of his critics saying ‘‘he’s a fascist.’’

Trump deleted his retweet Tuesday after about five minutes, but not before the message sent to his 35 million followers racked up a big response.

Trump seems to have been trying to draw attention to a Fox & Friends article on a possible presidential pardon for former Phoenix-area sheriff, Joe Arpaio, who was convicted of a crime for ignoring a US court order to stop traffic patrols that targeted immigrants.

A Twitter handle identified as ‘‘@MikeHolden42’’ tweeted to Trump ‘‘He’s a fascist, so not unusual.’’ The user suggested in subsequent tweets he was calling Trump a facist, not Arpaio.

Trump retweeted the message to his massive following, triggering an avalanche of replies. @MikeHolden42 responded: ‘‘I’m announcing my retirement from Twitter. I’ll never top this RT.’’ He later updated his description on Twitter as ‘‘Officially Endorsed by the President of the United States.’’

Associated Press Bannon’s future unclear

NEW YORK — President Trump won’t say whether he plans to keep Steve Bannon, a top adviser and key campaign strategist, in the White House.

‘‘We’ll see what happens with Mr. Bannon,’’ Trump said at an impromptu Tuesday news conference where he fielded questions about his confidence in his adviser.

Bannon, the former leader of conservative Breitbart News website, has been a contentious figure in a divided White House for months and has been viewed as on the outs before.
