New York - U.S. President Donald Trump’s longtime personal lawyer Michael Cohen revealed in court that Fox News host Sean Hannity was one of his clients after a federal judge overruled his effort to withhold the client’s identity.

Lawyers for Michael Cohen argued in court on Monday that they could not identify Hannity because he asked that his name not be disclosed in connection with an FBI seizure of Cohen’s files. But Judge Kimba Wood made one of the lawyers identify him in open court.

“I understand if he doesn’t want his name out there, but that’s not enough under the law,” Wood said, before ordering a lawyer for Cohen to disclose the name.

Sean Hannity is a conservative television host known for passionately advocating for Trump on his Fox News show.

The hearing in a New York City courtroom stems from a surprise raid this month on Cohen’s home and office.

The raid carried out at Cohen’s apartment, hotel room, office and safety deposit box sought bank records, records on Cohen’s dealing in the taxi industry, Cohen’s communications with the Trump campaign.

Assistant U.S. Attorney Tom McKay asked the judge Monday to require Michael Cohen to reveal more information about his clients, saying he isn’t forthcoming about his law practice.

He complained that Cohen won’t disclose the identity of one of them described as a “publicly prominent individual.”

The names of Cohen’s clients are at issue because the lawyer has argued that materials seized in the raid on his home and office are subject to attorney-client privilege.

Cohen’s lawyers said investigators “took everything” during raids last week on his residence and office. They called the search “completely unprecedented.”

At issue is exactly who gets to look at Cohen’s seized documents and devices before they are turned over to prosecutors. Attorneys for Cohen say they want first crack. Trump’s lawyers say they also want some form of prior review. Another option is to set up a “special master” who will vet the material to determine what is protected and what isn’t; that is the Cohen team’s second choice.

Prosecutors prefer the ordinary procedure of reviewing the documents with a panel of prosecutors unrelated to the investigation — a so-called “taint team.”

Trump said Sunday that all lawyers are now “deflated and concerned” by the FBI raid on Cohen.

“Attorney Client privilege is now a thing of the past,” he tweeted. “I have many (too many!) lawyers and they are probably wondering when their offices, and even homes, are going to be raided with everything, including their phones and computers, taken. All lawyers are deflated and concerned!”
