Former President Donald Trump on Wednesday filed a more than $500 million lawsuit in federal court against Michael Cohen, accusing his ex-lawyer-turned-nemesis of ruining his reputation by repeatedly "spreading falsehoods."

In the suit, Trump, through his lawyers, alleges that his former fixer Cohen breached his attorney-client relationship and profited off trashing the ex-president. 

Cohen "breached his fiduciary duties owed to [Trump] by virtue of their attorney-client relationship by both revealing [Trump's] confidences, and spreading falsehoods about [Trump], likely to be embarrassing or detrimental, and partook in other misconduct," says the suit filed in the US District Court for the Southern District of Florida.
