The cease-and-desist notice accuses Mr Bannon of defaming the president in speaking to author Michael Wolff.
Wolff’s forthcoming tell-all book describes the president as being unprepared for the job.
Mr Trump responded by saying Mr Bannon had “lost his mind” after losing his White House position.
His lawyers said Mr Bannon had broken his employment agreement by speaking to Wolff about Mr Trump and his family, “disclosing confidential information” and “making disparaging statements and in some cases outright defamatory statements to Mr Wolff about Mr Trump, his family members, and the Company”.
