Trump legal team blasts explosive Michael Wolff book in cease-and-desist letter The book is scheduled to be released next week but excerpts have caused a stir.

 -- President Donald Trump’s lawyer, Charles Harder, has demanded on behalf of his client that author Michael Wolff and his publisher immediately “cease and desist from any further publication, release or dissemination” of a forthcoming book, “Fire and Fury, according to a letter obtained by ABC News.

The book is scheduled to be released next week but excerpts have caused a stir.

“We are investigating numerous false and/or baseless statements that you have made about Mr. Trump,” the lawyer wrote to Wolff.

The letter goes on to say they are looking into possible defamation of Trump and his family and invasion of privacy.

The lengthy letter to Wolff and Henry Holt and Co. Inc. goes on to accuse the author of actual malice.

It states, “Actual malice (reckless disregard for the truth) can be proven by the fact that the Book admits in the Introduction that it contains untrue statements. Moreover, the Book appears to cite to no sources for many of its most damaging statements about Mr. Trump. Also, many of your so-called ‘sources’ have stated publicly that they never spoke to Mr. Wolff and/or never made the statements that are being attributed to them. Other alleged ‘sources’ of statements about Mr. Trump are believed to have no personal knowledge of the facts upon which they are making statements or are known to be unreliable and/or strongly biased against Mr. Trump.”

Harder sent a similar letter to former White House chief strategist Steve Bannon Wednesday night demanding he cease and desist from making allegedly false statements against the president and his family.

Bannon has not responded to ABC News' request for comment.

Henry Holt and Company the publisher of “Fire and Fury” told ABC News on Thursday, “We can confirm we received the Cease and Desist letter.”

Earlier Wednesday, Trump hit back at Bannon in scathing comments, saying that when Bannon was fired "he not only lost his job, he lost his mind.”

President Trump's comments, which came in the form of a written statement from the White House, were in response to Bannon's strident criticism of Donald Trump Jr., Jared Kushner and Paul Manafort for sitting down with a group of Russians who promised damaging information against Hillary Clinton during the 2016 election in excerpts from Wolff's new book, "Fire and Fury: Inside the Trump White House".

“Steve Bannon has nothing to do with me or my Presidency. When he was fired, he not only lost his job, he lost his mind. Steve was a staffer who worked for me after I had already won the nomination by defeating seventeen candidates, often described as the most talented field ever assembled in the Republican party,” the president said in a statement. “Now that he is on his own, Steve is learning that winning isn’t as easy as I make it look. Steve had very little to do with our historic victory, which was delivered by the forgotten men and women of this country. Yet Steve had everything to do with the loss of a Senate seat in Alabama held for more than thirty years by Republicans. Steve doesn’t represent my base — he’s only in it for himself.”
