MSNBC hostLawrence ODonnellroasted CNNs Jake Tapper on Monday in a rare instance of mainstream anchors shooting inside the tent.Tapper on Sunday touted an "exclusive interview with President Donald Trump" that was conducted through text messaging. CNNs "State of the Union" anchor asked Trump about Hamas response to his ceasefire proposal, if Israeli Prime Minister Benjamin Netanyahu is on board and the government shutdown, but ODonnellsuggested Tapper was either duped by White House staffers or simply conducted lazy journalism."CNN presented a so-called interview that they cant even prove was Donald Trump. They called it breaking news, they called it an exclusive, new interview with President Trump. Thats what they called it, before the interviewer said this," ODonnellsaid before playing video of Tapper saying Trump answered his questions via "text."TAPPER ADMITS FEELING 'HUMILITY' ABOUT PAST BIDEN COVERAGE AS LIBERALS DISPARAGE NEW BOOK"What? You gave him the questions in writing? So now, instead of letting Trump hide behind a phone call, where we can at least know that its him talking, Donald Trump gets to hide behind the black screen of texting? We actually have no idea who texted the replies in that so-called interview," ODonnell said.The MSNBC host said "CNN is unable to prove" it was actually Trump responding."CNN has not revealed how long it took to get a reply to each of the five written questions that apparently got replies from someone," ODonnell said.ODonnell continued to belittle Tapper, suggesting "slow-pitch softball" questions were lobbed at the president. The MSNBC host was particularly bothered when Tapper asked, "How do you think the government shutdown is going to end?"ODonnell said Tapper received the "empty answer" he "deserved," and scolded his liberal media peer for not revealing which questions Trump failed to respond to.JAKE TAPPER'S CNN SHOW HITS LOWEST RATINGS SINCE 2015 DESPITE NEW BIDEN BOOK BUZZ, INTENSE PUBLICITY TOUR"What could be more relevant in reporting an exchange than that is supposed to be with the President of the United States, then, including the questions he refused to answer? We have no idea," ODonnell said.O'Donnell suggested Trump is suffering from mental decline and accused Tapper of helping out the White House communications staff."When the history of Donald Trumps mental decline is written, it will no doubt include that so-called interview yesterday as a turning point in Donald Trumps White House dealing with the challenge of Donald Trump trying to answer questions during this period of obvious mental decline for Donald Trump," ODonnell said."Donald Trump was allowed to become, by CNN, the first president in history to get questions in writing for an interview, questions that he could take home and then Donald Trump was allowed to take -- we dont know how much time to reply to those questions," he continued. "We do know CNN is still waiting for some of them."CLICK HERE FOR MORE COVERAGE OF MEDIA AND CULTUREODonnell wasnt finished firing his ire at Tapper and said "this particular interviewer" would be "outraged" if former President Biden had ever answered questions via text message."This particular interviewer wrote an entire book condemning Joe Biden because he didnt like the way Joe Biden answered questions. He thought Joe Biden wasnt up to the job of answering questions as a presidential candidate, particularly in the presidential debate," ODonnell said, referring to Tapper and Axios reporter Alex Thompson's book, "Original Sin: President Bidens Decline, Its Cover-Up, and His Disastrous Choice to Run Again."ODonnell even believes Tapper could have set a dangerous precedent."In the Sunday morning interview business, and it is a business, every time they lower their standards for Donald Trump, that becomes the new standard," ODonnell said.A CNN spokesperson defended Tapper."Jake Tapper is a journalist CNN journalists will always take any opportunity to ask questions of those in power and share what we learn with our audience," the spokesperson told Fox News Digital.Tapper said Tuesday on The Bulwark podcast he casually texted Trump and didnt expect to be lauded for the "achievement.""I would much prefer to be doing an interview with him in person, on-camera, but he has not given me an interview since that one in June 2016," Tapper said.Tapper also read the questions that Trump failed to respond to, which included thoughts about Hamas, Obamacare subsidies and whether he would commit to an interview.The White House did not immediately respond to a request for comment.
