President Donald Trump revived his rivalry with Michelle Wolf in light of the White House Correspondents’ Association’s decision to break with tradition and feature an author instead of a comedian for its upcoming annual dinner.

“So-called comedian Michelle Wolf bombed so badly last year at the White House Correspondents’ Dinner that this year, for the first time in decades, they will have an author instead of a comedian,” Trump tweeted Tuesday night, teasing that he may go as a result.

“Good first step in comeback of a dying evening and tradition,” he added.

Wolf was the featured speaker at the previous White House Correspondents’ Association Dinner in April. During her set, she targeted top Trump administration officials, including White House adviser Kellyanne Conway and press secretary Sarah Huckabee Sanders, who were at the dinner.

Wolf hit back at Trump nearly an hour and a half later, tweeting to the president, “I bet you’d be on my side if I had killed a journalist.”

She also mocked Melania Trump’s anti-bullying campaign by including the first lady’s campaign slogan, ”#BeBest.”

The association announced Monday that author Ron Chernow, who wrote a bestselling biography of Alexander Hamilton, will be the featured speaker during the White House Correspondents’ Association Dinner on April 27.

Wolf, whose performance at last year’s dinner created some controversy, called the association “cowards” over its decision.

“The media is complicit. And I couldn’t be prouder,” she tweeted.

After Wolf’s performance at the 2018 dinner, Trump called Wolf “filthy” and deemed the dinner “an embarrassment to everyone associated with it.”

The White House Correspondents’ Dinner was a failure last year, but this year was an embarrassment to everyone associated with it. The filthy “comedian” totally bombed (couldn’t even deliver her lines-much like the Seth Meyers weak performance). Put Dinner to rest, or start over! — Donald J. Trump (@realDonaldTrump) April 30, 2018

Margaret Talev, president of the White House Correspondents’ Association, also distanced the organization from Wolf in a statement to members that claimed her performance was not “unifying” and “not in the spirit” of the group’s mission.

In response, a number of journalists and comedians defended Wolf, arguing that the comedian roasted political figures from both sides.

Wolf stood by her performance, in which she called out Trump officials for repeatedly lying to the public.

“I wouldn’t change a single word that I said. I’m very happy with what I said, and I’m glad I stuck to my guns,” Wolf told NPR’s Terry Gross in late April.
