President Donald Trump isn't the only one who won't be attending the White House Correspondents' Association dinner this year.

Administration officials also won't be at the annual black-tie event, which takes place Saturday night, a White House official confirmed to NBC News on Tuesday.

"Instead, Saturday evening President Trump will travel to Green Bay, Wisconsin, where he will hold a campaign rally," the official said.

Politico first reported the boycott, which comes as Trump on Tuesday derided MSNBC's "Morning Joe" as "Morning Psycho"; blasted CNN as "a proven and long term ratings and beyond disaster"; asked whether The New York Times would "get down on their knees & beg for forgiveness" for its coverage; and praised Fox News' "Fox and Friends" as "by far the best of the morning political shows on television."

....Dumb and Sick. A really bad show with low ratings - and will only get worse. CNN has been a proven and long term ratings and beyond disaster. In fact, it rewarded Chris Cuomo with a now unsuccessful prime time slot, despite his massive failure in the morning. Only on CNN! — Donald J. Trump (@realDonaldTrump) April 23, 2019

Sorry to say but @foxandfriends is by far the best of the morning political shows on television. It rightfully has BY FAR the highest ratings, not even close. Morning Psycho (Joe), who helped get me elected in 2016 by having me on (free) all the time, has nosedived, too Angry... — Donald J. Trump (@realDonaldTrump) April 23, 2019

I wonder if the New York Times will apologize to me a second time, as they did after the 2016 Election. But this one will have to be a far bigger & better apology. On this one they will have to get down on their knees & beg for forgiveness-they are truly the Enemy of the People! — Donald J. Trump (@realDonaldTrump) April 23, 2019

Paul Krugman, of the Fake News New York Times, has lost all credibility, as has the Times itself, with his false and highly inaccurate writings on me. He is obsessed with hatred, just as others are obsessed with how stupid he is. He said Market would crash, Only Record Highs! — Donald J. Trump (@realDonaldTrump) April 23, 2019

This is the third consecutive year that the president will skip thenearly 100-year-old event. Trump said this month that he would not attend the dinner, telling reporters that it was “negative” and “boring."

The association's president, Olivier Knox, did not address the White House boycott in a statement Tuesday.

"We’re looking forward to an enjoyable evening of celebrating the First Amendment and great journalists past, presen, and future," Knox said, repeating the statement he made when Trump announced he would not attend.

The dinner, which celebrates the First Amendment and raises scholarship money for budding journalists, is no stranger to controversy; last year, comedian Michelle Wolf drew criticism for ridiculing White House press secretary Sarah Sanders, as well as other administration officials, in her monologue.

Wolf, a former correspondent on Comedy Central’s “The Daily Show,” compared Sanders to a ruthless figure in the dystopian show “The Handmaid’s Tale.” She added that Sanders “burns facts and then she uses that ash to create a perfect smoky eye,” referring to her make-up.

Others, including many fellow comics, defended Wolf's act, which also ribbed Democrats and the media, saying she spoke truth to power and spared no one.

The correspondents' association, however, issued a statement saying the comedian’s monologue “was not in the spirit” of its mission. Wolf has since said she does not regret her performance.

In response to the backlash, the association announced in November that it would break with the tradition of having a comedian host the event and roast the Washington elite. Instead, the biographer Ron Chernow, author of comprehensive tomes about Alexander Hamilton, George Washington and Ulysses S. Grant, will be the featured speaker.
