Donald Trump’s campaign CEO fired a new mother suffering from multiple sclerosis while she was on maternity leave, according to a lawsuit obtained exclusively by The Post.

“Julia Panely-Pacetti, a new mother who suffers from multiple sclerosis, was terminated by defendants from her position as head of public relations and corporate marketing because of her sex and her disability,” states the lawsuit, filed in Manhattan federal court in September 2005.

The action was filed against American Vantage Companies, Panely-Pacetti’s then-employer, where she reported directly to Stephen Bannon, Trump’s top adviser and the chief of Breitbart News.

Panely-Pacetti claimed she was fired “while she was on a protected Family and Medical Leave Act maternity leave, even though she had been forced to continue performing her job responsibilities from home throughout her maternity leave,” the suit states.

News of the lawsuit comes just days after The Post exclusively reported that the man hired to remake Trump’s image roughed up and threatened his wife during their marriage, and also spanked their toddler twin girls, according to legal papers filed in their subsequent divorce case.

A September 2006 court document states the suit against Bannon was settled — but no details were made publicly available.

A spokeswoman for Bannon said: “Ms. Panely-Pacetti was not fired but laid off with all the personnel in her entire division during a corporate restructuring where the parent company exited its international sales and marketing business, and shutdown its communications department.”
