The author of a new book about the White House is contradicting Steve Bannon's explanation of comments that angered President Donald Trump.

Michael Wolff appeared Monday on MSNBC's "Morning Joe" to discuss "Fire and Fury: Inside the Trump White House."

In the book, Bannon described a meeting between Donald Trump Jr., senior campaign aides and a Russian lawyer as "treasonous" and "unpatriotic." Bannon, who is Trump's former chief strategist, sought to make amends Sunday, saying in statement that his description was aimed at former Trump campaign chairman Paul Manafort, not Trump's son.

Wolff says the comments were "directed directly at Don. Jr."

The book depicts the 45th president as a leader who doesn't understand the weight of his office and whose competence is questioned by aides. Trump has blasted the book as inaccurate.
