Earlier yesterday, Trump similarly lashed out at two other media organisations, ABC and CNN, that had issued corrections on stories about Trump in recent days.
"Fake News CNN made a vicious and purposeful mistake yesterday. They were caught red handed, just like lonely Brian Ross at ABC News (who should be immediately fired for his 'mistake'). Watch to see if @CNN fires those responsible, or was it just gross incompetence?" he tweeted.
Trump tweeted about the "GREAT EVENING last night" at his rally in Pensacola, Florida, where he told the audience, among other things, to "get out and vote for Roy Moore," Alabama's Republican nominee for US Senate, who has been accused of sexual misconduct with teenage girls. "Arena was packed to the rafters, the crowd was loud, loving and really smart," Trump wrote.
A short time later, Weigel quoted Trump's tweet and wrote "Packed to the rafters," attaching a photo that showed hundreds of available seats in the lower and upper levels. He deleted it about 20 minutes later.
Trump addressed Weigel's tweet with his own: ".@DaveWeigel @WashingtonPost put out a phony photo of an empty arena hours before I arrived @ the venue, w/ thousands of people outside, on their way in. Real photos now shown as I spoke. Packed house, many people unable to get in. Demand apology & retraction from FAKE NEWS WaPo!" the President wrote, including pictures of the venue's seats filled as he was onstage.
Weigel tweeted back almost immediately. "Sure thing: I apologise. I deleted the photo after @dmartosko told me I'd gotten it wrong," Weigel wrote, referring to David Martosko, US political editor of the Daily Mail's website. "Was confused by the image of you walking in the bottom right corner."
In a later tweet, Weigel wrote: "It was a bad tweet on my personal account, not a story for Washington Post. . . . Very fair to call me out."
Among Trump's grievances with the media, he is notably sensitive about crowd size at his events.
After images circulated on social media in January that showed fewer people at his inauguration than former President Barack Obama's, then-press secretary Sean Spicer was dispatched to tell the press, "This was the largest audience to ever witness an inauguration - period - both in person and around the globe."
