But comedians on the late-night TV circuit were quick to point out that Trump's promise came just days after he made a failed attempt to stop the publication of Michael Wolff's tell-all book, "Fire and Fury: Inside the Trump White House".
Portraying Donald Trump's orange hair as a giant flame, the magazine cover depicts what has often been a tumultuous and controversial year for the president.
When the conversation shifted to Donald Trump's mental fitness, Michael Wolff insisted that everyone he spoke to on staff expressed some sort of concern for the president's well-being. In a letter to Wolff and the book's publisher, Trump's lawyers demanded the halting of the book's publication and "a full and complete retraction and apology".
"We're going to take a very, very strong look at that", he said.
Nikki Haley, the US ambassador to the United Nations, said she visits the White House once a week, and "no one questions the stability of the president".
Wolff said that the presidency is known to magnify the office holder in extreme ways and this is what's happened with Trump.
But with so many books about President Trump coming out, Fell said it's hard to know which ones will be more popular than others, making it difficult to know how many to order. For now, I'll go with the final paragraph of the Politifact.com article.
Bannon left the White House last summer.
Kayli Vandermeer has been fielding daily requests for the book that has thrown the White House into disarray and has continued to generate Twitter fits from the commander-in-chief.
"So then you had to go and speak to another person and that became a kind of thing, give me your version of this story", Wolff said.
"They forget that they don't really have control of the outcome... it's in keeping that [Bannon] would have sort of wanted to glorify himself to this reporter and he thought that's how it would be done", Lindorff added. "While he can say what he wants, thankfully the President cannot change our laws, much less amend the Constitution".
Last Wednesday, however, it was revealed that Bannon had accused the president's son, Donald Trump Jr. of "treason" for meeting with Russian officials. "Now I have to put up with a Fake Book, written by a totally discredited author".
"Fire and Fury" is based on Wolff's series of interviews with those involved in the Trump administration, and McNamara is confident that it is "an accurate report on events of vital public importance".
