A source close to Donald Trump has revealed that the former president filed a lawsuit on Wednesday against his ex-attorney, Michael Cohen, demanding more than $500 million in damages.

“This is an action arising from [Cohen’s] multiple breaches of fiduciary duty, unjust enrichment, conversion and breaches of contract by virtue of [Cohen’s] past service as [Trump’s] employee and attorney,” the lawsuit first obtained by Fox News reads.

The 30-page legal filing submitted to the U.S. District Court for the Southern District of Florida accuses Cohen of breaching attorney-client privilege and unjustly enriching himself at Trump’s expense.
