When President Donald Trump is under attack, expect Dallas megachurch pastor Robert Jeffress to rush to his aid.

His latest defense of Trump came during a Fox News appearance Friday, when Jeffress slammed a controversial exposé by author Michael Wolff titled Fire and Fury: Inside the Trump White House.

Jeffress, the head of First Baptist Dallas and an adviser to the president, disputed the book's account that Trump did not want to win the election and that his wife, Melania, was distraught about the victory.

But he did agree with Wolff on one thing.

"If there is a kernel of truth in this book, it is the charge that President Trump is not 'normal.' He isn't normal, which is why the American people put him in office to begin with," Jeffress told Fox News @ Night host Shannon Bream. "The American people were tired of a normal that said we ought to accept subpar economic growth, that we ought to accept ISIS as continuing reality, that our best days were behind us."

He went on: "More and more Americans are grateful that the president isn't 'normal' and has established a new normal in America."

Wolff's book has stirred questions about Trump's fitness for office as it describes people in his inner circle calling him a moron and an idiot.

The journalist says that the president is "semi-literate" and that aides struggle to capture his attention because he's easily bored and won't read briefings or watch slideshows.

Trump has chafed at this portrayal.

"Actually, throughout my life, my two greatest assets have been mental stability and being, like, really smart," the president tweeted Saturday.

....Actually, throughout my life, my two greatest assets have been mental stability and being, like, really smart. Crooked Hillary Clinton also played these cards very hard and, as everyone knows, went down in flames. I went from VERY successful businessman, to top T.V. Star..... — Donald J.

....to President of the United States (on my first try). I think that would qualify as not smart, but genius....and a very stable genius at that! — Donald J. Trump (@realDonaldTrump) January 6, 2018

Fire and Fury recounts moments of shock among Trump's family as it became clear he was going to win the presidency. Melania Trump, who had been concerned about giving up her sheltered life, was in tears, according to Wolff's account.

Jeffress said on Fox News that he had been with the president at Trump Tower in Manhattan on Election Day and described Trump and his wife as "relaxed and optimistic." There were no tears, he said.

"Admittedly, I didn't spend all day with the Trumps," Jeffress said. "I didn't spend most of the day with the Trumps, but I spent more time with the Trumps than Michael Wolff did, and I can tell you, that's just an inaccurate portrayal."

Wolff has said he logged about three hours interviewing Trump, in addition to dozens of other interviews with his senior staff.

White House Press Secretary Sarah Huckabee Sanders told reporters on Wednesday that Wolff's only interaction with the president was a brief phone call that was unrelated to the book.

Wolff's book has come under scrutiny, and not only by the White House. Some journalists have pointed out inaccuracies. For example, a passage details how Trump apparently didn't know who former House speaker John Boehner was when the name was suggested to him as a potential chief of staff, but, as The Washington Post points out the men have played golf together and Trump mentioned Boehner during the campaign.

In another passage, Wolff confused Post reporter Mark Berman with lobbyist Mike Berman (no relation), mistakenly claiming that the former was eating breakfast at a hotel where first daughter Ivanka Trump was making the rounds.

Maggie Haberman, the White House correspondent for The New York Times, tweeted that the book was "light in fact-checking."

Thin but readable. Well written. Several things that are true and several that are not. Light in fact-checking and copy-editing. — Maggie Haberman (@maggieNYT) January 3, 2018

Wolff was a regular presence at the White House, often seen with then-chief strategist Stephen Bannon, according to news reports.

Jeffress is also a frequent guest at the White House. He's a member of the president's evangelical advisory group and was photographed with the Trumps leading a prayer in December. He also preached at a service Trump attended on Inauguration Day.
