Washington Post reporter Dave Weigel has apologized to President Trump on Twitter after Trump lambasted him for posting a photo from before his rally in Pensacola, Florida, Friday night.

The backstory: The photo Weigel posted spread quickly online, with Weigel and others thinking it showed the moment Trump took the stage. In fact, it was before the event began. Trump has attacked reporters for not owning up to mistakes in coverage; Weigel tweeted Saturday night that "it was a bad tweet on [his] personal account, not a story for the Washington Post," and it's "very fair" for Trump to call him out.

.@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! pic.twitter.com/XAblFGh1ob— Donald J. Trump (@realDonaldTrump) December 9, 2017

Sure thing: I apologize. I deleted the photo after @dmartosko told me I'd gotten it wrong. Was confused by the image of you walking in the bottom right corner. https://t.co/fQY7GMNSaD— Dave Weigel (@daveweigel) December 9, 2017
