Former Arkansas Gov. Mike Huckabee spoke out Wednesday on The Intelligence Report against the frequent use of anonymous sources in veteran reporter Bob Woodward's new book about Trump's White House.

Excerpts from an early copy of the book, titled "Fear: Trump in the White House," were reported on Tuesday by The Washington Post, portraying a chaotic Trump White House in which the president is bad-mouthed by members of his staff.

The president on Wednesday called the book "total fiction" and said that Defense Secretary Jim Mattis and Chief of Staff John Kelly were both "insulted" by what Woodward wrote about them.

Huckabee said that Woodward has a history of using anonymous sources for his work and "hurriedly" trying to publish a book for media attention.

Huckabee said, too, that an author using anonymous sources is a "gutless coward."

"It's a gutless coward who will not stand up and be counted for what he or she says has happened," he said. "If you can't go on the record, then just don't be believed."

According to The Post, Woodward's book alleges that Mattis told associates of President Trump that the president had the understanding of “a fifth- or sixth-grader.”

After Syrian dictator Bashar al-Assad launched a chemical attack on Syrians in April 2017, Trump is said to have demanded Mattis launch an assassination attempt.

Trump said Wednesday that such a demand was "never discussed" and accused Woodward of writing false and "scandalous" things about other presidents, including George W. Bush and Barack Obama.

Huckabee said Wednesday that if a journalist can't verify an anonymous source's tip, it's "nothing short of a hit-and-run."
