Input: New York (CNN) The White House Correspondents' Association is shelving its tradition of having a comedian roast the president and the press corps at its annual fundraising dinner. Instead, famed author Ron Chernow will be the featured speaker. 
  
 The association's president Olivier Knox made the announcement on Monday. For several months, he had been leaning against inviting a comic, and he had been conferring with other members about the change. 
  
 The dinner is a key date on Washington's social calendar. But its meaning has changed amid constant attacks on the media and increasing political polarization. Booking Chernow instead of a stand-up performer is a recognition that the annual dinner changes dramatically when the president isn't there. 
  
 President Trump has snubbed the event two years in a row, and there is little reason to believe that he will attend next dinner, which is scheduled for April 27, 2019. 
  
 So the association had to rethink things. 
  
 Historically, Knox told CNN earlier this year, "when the president comes, the program's center of gravity naturally tilts toward the president." After he speaks and ribs the press corps, the featured comedian serves as the counter-balance. But with the president absent, the dinner has a different, more combative feel. 
  
 Knox and the association's board members are trying to change that. 
  
 "As we celebrate the importance of a free and independent news media to the health of the republic, I look forward to hearing Ron place this unusual moment in the context of American history," Knox said in a statement on Monday. 
  
 Chernow is the author of six books, including best selling titles about Alexander Hamilton and George Washington. The Hamilton biography inspired Lin-Manuel Miranda's Broadway hit musical "Hamilton," and Chernow served as a historical consultant on the production. 
  
 Chernow said in a statement, "The White House Correspondents' Association has asked me to make the case for the First Amendment and I am happy to oblige. Freedom of the press is always a timely subject and this seems like the perfect moment to go back to basics. My major worry these days is that we Americans will forget who we are as a people and historians should serve as our chief custodians in preserving that rich storehouse of memory. While I have never been mistaken for a stand-up comedian, I promise that my history lesson won't be dry." 
  
 Comedienne Michelle Wolf spurred debate about the dinner format when she performed at last April's dinner. 
  
 Afterward, Trump allies claimed that the jokes proved the press corps' hatred of Trump. Trump tweeted that the dinner was "embarrassing" and the event is "dead." 
  
 But many writers, activists and comedians defended Wolf for roasting both the administration and the media. 
  
 Wolf seemed happy about the outcome. When former press secretary Sean Spicer tweeted that the dinner "was a disgrace," Wolf replied, "Thank you!" 
  
 The correspondents' association -- which did not vet her monologue ahead of time -- expressed regret that the controversy over the jokes overshadowed the dinner's First Amendment message. 
  
 Members of the association serve one-year terms as president. The president back then, Margaret Talev, said she invited Wolf because "she was a talented comedian with a message to deliver." But Talev also said Wolf's stand-up act did not reflect the "spirit" of the association's mission. 
  
 Knox took over as president of the association in July. His day job is chief Washington correspondent for SiriusXM. He leads the group's advocacy for press access and other White House issues. In the past week, the association has supported CNN in litigation with the White House over Jim Acosta's press pass. 
  
 After Knox's term as president, Jon Karl of ABC News will take over next July. 
  
 Then it will be Karl's turn to decide whether to invite a comedian, an author, or someone else for the 2020 dinner. 
  
 But the decision about 2019 has already stirred lots of debate, with some journalists praising the pick and others saying it was a capitulation to Trump. 
  
 Wolf left no doubt about her point of view. 
  
 She tweeted, "The @whca are cowards. The media is complicit. And I couldn't be prouder." ||||| Anti-Trump comedian Michelle Wolf called the White House Correspondents' Association “cowards” for ditching comedy for its annual dinner in 2019 after she made headlines with a crude performance last April. 
  
 “The @whca are cowards. The media is complicit. And I couldn't be prouder,” Wolf tweeted after the WHCA announced that Alexander Hamilton biographer Ron Chernow would be the featured speaker at the annual dinner, which is scheduled for April 27. 
  
 “I’m delighted that Ron will share his lively, deeply researched perspectives on American politics and history at the 2019 White House Correspondents’ Dinner,” WHCA President Olivier Knox said. “As we celebrate the importance of a free and independent news media to the health of the Republic, I look forward to hearing Ron place this unusual moment in the context of American history.”

 The role of the host is typically to roast the president and members of the media, with the jokes sometimes taking shots at the most powerful person in the world. But many critics felt Wolf took it too far last year when she launched attacks on President Trump and members of his administration. 
  
 Chernow is far from a comedian, but has written acclaimed biographies of prominent figures such as Alexander Hamilton, George Washington and John D. Rockefeller.

 “The White House Correspondents’ Association has asked me to make the case for the First Amendment and I am happy to oblige,” Chernow said. “Freedom of the press is always a timely subject and this seems like the perfect moment to go back to basics. My major worry these days is that we Americans will forget who we are as a people and historians should serve as our chief custodians in preserving that rich storehouse of memory. While I have never been mistaken for a stand-up comedian, I promise that my history lesson won’t be dry.” 
  
 It didn’t take long for watchdogs to blame Wolf’s performance for the change in format. 
  
 “Way to ruin it for everyone Michelle Wolf,” Mediaite editor Colby Hall wrote. 
  
 “Michelle Wolf didn't just kill her career, she killed the WHCA dinner entertainment too,” Erick Erickson tweeted. 
  
 The WHCA includes a large roster of news organizations such as Fox News, the Associated Press, NBC, CBS, ABC, Reuters, CNN, Wall Street Journal, Bloomberg, NPR, Washington Post, The New York Times, USA Today and Politico.

 Several attendees of the 2018 event sat in stunned silence as Wolf took personal jabs at Press Secretary Sarah Sanders, who was at the dinner as a representative of the Trump administration and sat just feet away as Wolf commented on her appearance, criticized her job performance and even her Southern roots. 
  
 Several journalists came to Sanders’ defense after Wolf attacked Sanders’ looks. The New York Times’ Maggie Haberman even commended Sanders for absorbing “intense criticism” brought on by Wolf. Anti-Trump “Morning Joe” co-host Mika Brzezinski called Wolf’s jokes on Sanders “deplorable” and said the WHCA owed Sanders an apology, while NBC News’ Andrea Mitchell said Wolf’s routine was the “worst since [Don] Imus insulted [the] Clintons” during the 1996 Radio-Television Correspondents Dinner. 
  
 President Trump – who was not in attendance -- called the event a “big, boring bust” and declared the "so-called comedian really bombed.” The annual dinner is traditionally attended by the president and first lady, but the Trumps have skipped the event. 
  
 “The Break with Michelle Wolf” debuted on Netflix shortly after the dinner but was canceled months later. During the run of her now-canceled show, Wolf took aim at first daughter Ivanka in another series of crude jokes. She has also referred to Eric Trump as “an abortion,” compared ICE to ISIS and even joked that the president abused Melania Trump.

Output:
Looks like President Trump won't have to deal with jokes made at his expense at this year's White House Correspondents' Dinner, because the White House Correspondents' Association didn't invite a comedian. Instead, author Ron Chernow will speak at the annual event, to be held April 27, CNN reports. The historian has written popular biographies of George Washington, Ulysses S. Grant, and others; his book about Alexander Hamilton inspired Lin-Manuel Miranda to write the Broadway musical Hamilton. Traditionally, the POTUS attends the WHCA dinner; he ribs the press and then the comedian ribs him. But Trump has not attended either of the two dinners that have taken place so far since he took office, giving the dinner a more combative feel, association president Olivier Knox explained to CNN. After last year's controversial monologue by comedian Michelle Wolf, the association's then-president said Wolf's remarks took the focus away from the First Amendment freedoms the night is supposed to be celebrating. (Indeed, some commentators were quick to blame Wolf for causing the change, Fox News reports.) This year, "as we celebrate the importance of a free and independent news media to the health of the republic, I look forward to hearing Ron place this unusual moment in the context of American history," Knox says in a statement. Adds Chernow, "The White House Correspondents' Association has asked me to make the case for the First Amendment and I am happy to oblige. Freedom of the press is always a timely subject and this seems like the perfect moment to go back to basics." He says that though he's no comedian, he promises not to be "dry."
