UPDATE

11:59 AM PT — According to reports, Cohen's attorney revealed in court the mystery third client was Sean Hannity. The Fox News host responded on Twitter, saying, "Michael Cohen has never represented me in any matter. I never retained him, received an invoice, or paid legal fees. I have occasionally had brief discussions with him about legal questions about which I wanted his input and perspective."

He added, "I assumed those conversations were confidential, but to be absolutely clear they never involved any matter between me and a third-party."

Michael Cohen has a mystery client he's done legal work for in the last two years that he is trying to protect the identity of as the U.S. government prepares to go through the documents seized from him last week.

According to court documents obtained by The Blast, Cohen says he had 10 clients he did work for in 2017 and 2018. Seven of those his clients, he claims, were simple cases where he gave "strategic advice and business consulting, for which privilege would not attach."

But the three other clients are cases where he gave "more direct legal advice or dispute resolution." Cohen says of these clients:

One of these legal clients is Donald J. Trump. Another legal client is Elliot Broidy. The third legal client directed Mr. Cohen to not to reveal the identity publicly. Upon information and belief, the unnamed legal client’s matters are responsive to any matter covered by Attachment A of the search warrants.

Cohen believes that even revealing the name of this third client would violate attorney-client privilege. He states, "As to the one unnamed legal client, we do not believe that Mr. Cohen should be asked to reveal the name or can permissibly do so."

Broidy is the now-former deputy finance chair of the Republican National Committee who used Michael Cohen to arrange the payment of $1.6 million to a former Playboy model that Broidy had an affair with.

Cohen is due in court to argue over the fate of the thousands of documents seized in last week's raid.
