Trump earlier on Sunday took to Twitter to complain about a lack of coverage of recent errors in stories published by various news outlets.

Errors by CNN, ABC and The Washington Post have been widely covered in the media, with a full segment on CNN on Sunday dedicated to discussing the effect of reporting errors.

Trump has ramped up his attacks on the press in recent days, calling for individual reporters at The Washington Post and ABC News to be fired over the errors.

Trump referred to ABC News's Brian Ross as a "fraudster" on Friday, a week after he reported that Trump had directed his former national security adviser Michael Flynn to make contact with Russian officials during the campaign.

Ross was suspended for four weeks without pay over the error.

Trump targeted Washington Post reporter Dave Weigel on Saturday, demanding that he apologize for tweeting a photo of an empty arena before a Trump rally in Florida that had been taken hours before the event started.

Weigel deleted the image and apologized.

Trump also ripped CNN during his rally on Friday in Florida, one day after the network was forced to make a correction regarding a report on Donald Trump Jr. and WikiLeaks.
