Cannes, France 
 
 At the Cannes Lions advertising festival in the south of France, Fire and Fury author Michael Wolff spoke onstage today with Jeff Goodby, the cofounder of Goodby, Silverstein & Partners, a San Francisco-based ad agency. Wolff testified to Donald Trump’s ability to sell books. (Wolff’s chronicle of Trump’s first nine months as president, which was released in January, remains at the top of Amazon’s bestseller list.) US vice president Mike Pence, he said, was another story. 
 
 “When Mike Pence becomes the president—which I believe that he will become—the media business goes into a deep depression,” said Wolff. “Mike Pence is literally the most boring man on earth.” 
 
 “He’s not even mentioned in your book!” observed Goodby. 
 
 “Faceless. He’s so faceless,” said Wolff. “Even in the White House they only talk about Pence’s wife. Mother, she is called.” 
 
 “He calls her mother?” said Goodby. 
 
 “Everyone in the White House calls her mother,” said Wolff. ||||| File this one under “not a surprise.” 
 
 Michael Wolff predicts a bleak future for Donald Trump — and the media. 
 
 The “Fire & Fury” author predicted before a packed house at the Cannes Lions International Festival of Creativity on Monday morning that President Trump will be ousted from the White House in short order. 
 
 “We will soon find ourselves in the mother of all constitutional crises … When [Vice President] Mike Pence becomes president, which I believe that he will become, the media business goes into a deep depression,” Wolff said. “Mike Pence is literally the most boring person on Earth. He’s faceless.” 
 
 A nonchalant Wolff delivered the news, while basking in the success of his colorful, bestselling book that describes Trump’s dysfunctional White House. 
 
 The book has sold over 2 million hard copies in the US since its Jan. 5 release — plus millions of e-copies. 
 
 Wolff’s explosive book’s rise was meteoric. On Jan. 4, the day that The Guardian leaked excerpts from “Fire & Fury,” Wolff saw pre-sales of his book skyrocket to No. 1 on Amazon’s bestseller’s list within hours. Soon after, the White House sent a cease-and-desist letter, which boosted sales even higher. 
 
 Wolff has since cashed in on what he called the “aberrant entertainment” that is the Trump presidency, and will soon see his book turned into a 10-part television series directed by Jay Roach. He is also planning on penning a sequel, according to reports. 
 
 “Once a day, I cast my eyes heavenward and say, ‘Thank God for Donald Trump,’” the journalist said. 
 
 Despite the massive success, Wolff threw a few jabs at his competitors, who have questioned the accuracy of the gossipy tome. 
 
 “The press corps over there, the Washington political reporters, they do a different thing than I do,” he said with a touch of arrogance. “They are all very resentful that I got this story and I made all this money.” 
 
 What Wolff did was observe the administration at work for seven months. 
 
 “I never asked a question beyond, ‘How’s it going?,’” he said. “It’s an older style of reporting.” 
 
 To be sure, there were plenty of errors in the book — which sparked a lot of the pushback. 
 
 Wolff didn’t leave Cannes’ main stage before getting in a jab at the New York Times for its scoop that the president threatened to fire special counsel Robert Mueller, who is heading the investigation into the Trump campaign’s Russia ties. 
 
 “Every day he tried to fire Mueller. He did this constantly, to virtually everyone,” Wolff said smugly. “So the Times story was not wrong, but the Times story missed that fact.” ||||| Breaking News Emails Get breaking news alerts and special reports.

 Michael Wolff, the author of a new book that gives a behind-the-scenes account of the White House, defended his work Friday, insisting he spoke with President Donald Trump on the record and calling the commander in chief "a man who has less credibility than, perhaps, anyone who has ever walked on earth." 
 
 Wolff, in an exclusive interview on NBC's "Today," said that everyone he spoke to for the book, "Fire and Fury: Inside the Trump White House," described the president the same way. 
 
 "I will tell you the one description that everyone gave, everyone has in common: They all say he is like a child," Wolff explained. "And what they mean by that is, he has a need for immediate gratification. It is all about him." 
 
 Wolff added that "100 percent of the people around" Trump, "senior advisers, family members, every single one of them, questions his intelligence and fitness for office." 
 
 Trump hit back in a tweet late on Friday, claiming Wolff made up stories and used his former chief strategist "Sloppy Steve Bannon" to sell the book. 
 
 Michael Wolff is a total loser who made up stories in order to sell this really boring and untruthful book. He used Sloppy Steve Bannon, who cried when he got fired and begged for his job. Now Sloppy Steve has been dumped like a dog by almost everyone. Too bad! https://t.co/mEeUhk5ZV9 — Donald J. Trump (@realDonaldTrump) January 6, 2018 
 
 Wolff also contended that he "absolutely" spoke to the president during his reporting of the book. 
 
 "Whether he realized it was an interview or not, I don’t know, but it certainly was not off the record," Wolff said. "I spoke to him after the inauguration, yes. And I had spoken to, I mean I spent about three hours with the president over the course of the campaign and in the White House, so my window into Donald Trump is pretty significant." 
 
 Trump, however, said on Twitter Thursday night that he "authorized Zero access to White House" for the author and "never spoke to him for book." 
 
 Responding to Trump, Wolff said Friday that Trump isn't one to talk when it comes to credibility. 
 
 "My credibility is being questioned by a man who has less credibility than, perhaps, anyone who has ever walked on earth at this point," Wolff said. 
 
 Wolff added that he has the evidence to back up his work. 
 
 "I work like every journalist works so I have recordings, I have notes," Wolff said. "I am certainly and absolutely in every way comfortable with everything I’ve reported in this book." 
 
 "Fire and Fury" features behind-the-scenes anecdotes from Trump's White House, including details on how the most powerful men and women in Washington worked to make Trump president — and then turned on one another after he took the oath of office. 
 
 Wolff writes in the book, and explained during his “Today” interview, that top aides said at various points Trump that is “a moron, an idiot.” 
 
 “Actually there’s a competition to sort of get to the bottom line here of who this man is. Let’s remember, this man does not read, does not listen. So he’s like a pinball, just shooting off the sides,” Wolff said.

 Wolff also revealed how people around the president noticed an apparent decline in his mental stamina. 
 
 “In the beginning, it was like every 25 or 30 minutes, you would get the same three stories repeated," Wolff said about Trump. "Now it’s the same three stories in every 10 minutes." 
 
 Wolff was then asked to elaborate on an anecdote he described in an article in The Hollywood Reporter this week in which he said Trump, at his Mar-a-Lago resort in Florida over the winter holiday break, didn't recognize old friends. 
 
 "I will quote Steve Bannon — he’s lost it," Wolff said, referring to Trump's former strategist. 
 
 White House Press Secretary Sarah Huckabee Sanders, appearing on Fox News Friday morning, said it was "outrageous to make these types of accusations" about Trump's mental health. 
 
 It's "sad that people are going and making these desperate attempts to attack the president," she added. 
 
 Widely reported excerpts from the book have roiled Washington, including claims from Bannon that Donald Trump Jr.'s meeting with Russians at Trump Tower in June 2016 was "treasonous" and "unpatriotic." 
 
 The president apparently referred to Bannon as "Sloppy Steve," on Twitter Thursday night. On Friday afternoon, as he left the White House for a weekend at Camp David, he ignored shouted questions from reporters about whether he had read the book himself yet. 
 
 Wolff’s book was released early Friday by Henry Holt, which announced a day earlier that it was pushing up the publication date due to demand. Earlier Thursday, Trump attorney Charles Harder demanded in a letter sent to Wolff and his publisher that the book not be published or disseminated. The book reached No. 1 on the Amazon best-seller list Wednesday. 
 
 A copy of the letter obtained by NBC News cites defamation, libel and "actual malice" among the alleged wrongdoings in the book. 
 
 NBC News has not confirmed much of the book. Wolff has been accused in the past of suspect reporting, most notably in his 1998 book "Burn Rate." In its review, the now-defunct media journal Brill's Content cited 13 people depicted in the book as saying that Wolff invented or changed quotations and that they couldn't recall his taking any notes or recording their interviews.
– Fire and Fury author Michael Wolff had some amusing tidbits to share about the VP during an appearance at the Cannes Lions advertising festival Monday, Quartz reports. While President Trump sells books—Fire and Fury, which details his first nine months as POTUS, is still a bestseller after being released in January—Mike Pence, not so much. "When Mike Pence becomes the president—which I believe that he will become—the media business goes into a deep depression," Wolff predicted. "Mike Pence is literally the most boring man on earth." Wolff predicts Pence will get a job promotion due to Trump being booted from office, the New York Post reports. Wolff went on to say that Pence is "faceless" even at work: "Even in the White House they only talk about Pence’s wife. Mother, she is called." Jeff Goodby, the ad agency cofounder onstage with Wolff, asked whether Pence really calls his wife "Mother." Wolff's response: "Everyone in the White House calls her Mother." Rolling Stone first reported back in 2017 that Pence refers to wife Karen as "Mother." Politifact has since spoken to a number of people who say they've witnessed him calling her that, but since the site couldn't find "video or other documentary evidence," it has not rated the claim as true.
