NEW YORK — Michael Cohen’s mysterious third client, whose identity he tried to keep secret, has been revealed as Fox News host Sean Hannity.

Hannity’s name was disclosed in federal court in Manhattan on Monday afternoon on orders from U.S. District Court Judge Kimba Wood, eliciting gasps in the courtroom. Cohen’s legal work for President Trump and for a prominent Republican fundraiser, Elliott Broidy, involved payments to women to keep them quiet about sexual relationships.

It was not immediately clear what legal work Cohen did for Hannity, who tweeted:

“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.

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

Attorneys for Cohen and President Trump are trying to control access by prosecutors to documents and electronic devices that were seized in an April 9 FBI raid on Cohen’s home, office, and a hotel where he was staying. That raid was the result of a criminal investigation that involved Cohen’s personal business dealings and payments to two women on behalf of Trump.

Before revealing the client was Hannity, Cohen’s attorneys said it was “a publicly prominent individual” who was concerned about having his name released to the public and had specifically asked them to try to keep his name secret. One of Cohen’s lawyers told Wood he did not want to reveal the name of Cohen’s third client because “no one would want to be associated that they had been a client … in this way.” He did not specify exactly what he meant by that. Wood ultimately instructed Cohen’s team to reveal the name of his third client.

“Your honor, the client’s name that’s involved is Sean Hannity,” said one of Cohen’s lawyers.

Hannity did not immediately respond to an email from Yahoo News asking what type of legal work Cohen did for him and why he was concerned about his name being released. Hannity has been a staunch defender of both Trump and Cohen on the airwaves.

In court on Monday, Cohen’s attorneys argued that he needs to review the documents taken in the raid, as they may contain privileged communications. If he is not allowed to review the documents, they proposed that a special master be appointed to examine the documents before prosecutors. As of this writing, the hearing is ongoing.

Assistant U.S. Attorney Thomas McKay was the first to raise the issue of Cohen’s mysterious third client. He said Cohen’s failure to identify the person was an indication Cohen and his team would make an “inevitably overbroad claim of privilege” if they were allowed to review the documents seized in the raid.

“The continued resistance to provide the court with facts and names is just a preview of what would come if the court accepted Cohen’s proposal,” McKay said.

McKay also defended the raid against claims by Cohen’s team that it was an unreasonable search.

“The was nothing improper about the way the search warrant was executed,” McKay said.

McKay noted the warrant was executed because a judge found probable cause it could uncover evidence of a crime, and that it is typical of white-collar cases to involve searches that could include some privileged communications. The judge, he said, would have been aware of that possibility.
