A legal fight over what should happen to records the FBI seized from US President Donald Trump's personal attorney took a surprise twist Monday when the lawyer, Michael Cohen, was forced to reveal a secret _ that he had also done legal work for Fox News host Sean Hannity.

The disclosure came as a New York judge disappointed a lawyer for Trump by letting prosecutors proceed with the cataloguing of evidence including multiple electronic devices that were seized in raids while a system is set up to ensure they are protected by attorney-client privilege.

Lawyers for Cohen and prosecutors had reason to claim success after three hours of arguments left U.S. District Judge Kimba Wood saying she may appoint a special master to help decide how much of the materials are subject to the privilege.

The only disappointed party seemed to be Trump's attorney, Joanna Hendon, who said she was objecting to any plan by prosecutors to search for how many times Trump's name appears in documents as they try to decide how many might be subject to attorney-client privilege.

Prosecutors promised not to study the contents of the materials while the process of protecting privileged materials is resolved.

Wood also denied Hendon's request that lawyers for Trump and Cohen get the first crack at designating documents and other evidence that might be subject to the privilege.

The Hannity revelation came after Wood required Cohen to divulge the names of the clients he's worked with since the 2016 election.

One, of course, was Trump himself.

Another was Elliot Broidy, a Trump fundraiser who resigned from the Republican National Committee on Friday after it was revealed that he paid $1.6 million to a Playboy Playmate with whom he had an extramarital affair. The Playmate became pregnant and elected to have an abortion.

With Cohen by their side on Monday, lawyers initially resisted revealing the name of the third client for privacy reasons, saying it would be embarrassing for the client and that the client had asked that they immediately appeal any request to divulge his name.

But Wood pressed on.

When the name was announced, there were gasps and some laughter in a courtroom packed with journalists. A few of them raced from the courtroom.

Cohen's lawyers did not detail the type of legal work he did for Hannity.

On his radio show, Hannity said Cohen was never involved in any matter between him and any third party.

Hannity, an outspoken supporter of Trump, has been a fierce critic of special counsel Robert Mueller, who is looking into Russian interference in the 2016 U.S. presidential election.

Monday's hearing began with an appearance by porn actress Stormy Daniels, who was swarmed by photographers and nearly fell as she was hustled into the courthouse, a scene that captured the sensational atmosphere around the case.

The last to enter court, she was among the first to leave.

While in court, she smiled several times as she observed the proceedings from a folding chair near the back of the room.

Outside afterward, she said Cohen has acted like he's above the law and that she and her lawyer are committed to making sure everyone learns the truth.

The April 9 raid on Cohen sought information on a variety of matters, including a $130,000 payment made to Daniels, who alleges she had sex with a married Trump in 2006.

"Prosecutors were saying that lawyers for Michael Cohen and President Donald Trump were just trying to delay proceedings by asking for a process where they would look at all the evidence that was seized last week first, and then decide what was not violated by attorney-client privilege, and what prosecutors could use in their criminal investigation. Prosecutors say that's not the way to do it. They want a process whereby attorneys for Donald... President Donald Trump and Michael Cohen have a role in the process but aren't able to control the process. The judge seems eager, she said, to make whatever occurs not to...not slow up the process so that the government can do what it needs to do in its investigation, and yet, the attorney-client privilege is protected."

"The judge did say that she may, and this is something that Michael Cohen's lawyers were requesting, that she may appoint a special master to at least have a limited role in deciding how the evidence is viewed and how they ultimately decide what is subject to attorney-client privilege. But she seemed also to be giving the government what it wants in letting the prosecutors, the special taint team they have –not their criminal prosecutors—get a look at all the evidence of putting it together so that they can hand it over to the attorneys for Michael Cohen and President Donald Trump to look at and for them to flag whatever they think should be subject to attorney-client privilege."

"Prosecutors revealed that when they did the raids on Michael Cohen's residence and his office, that they had numerous electronic devices, including telephones, and that for what they could, the computer devices, they actually took images. So, his lawyers, they say, already have much of the evidence and know what's there."

"The surprise moment in court came when the lawyers for Michael Cohen did not want to divulge one client who had asked to remain anonymous, saying that it could be embarrassing being associated with someone who's under criminal investigation. The judge forced them to divulge the name, it turned out to be Sean Hannity, a Fox News personality. And as soon as that name was announced, there was an audible gasp in the courtroom that's largely crowded with journalists, and some journalists immediately ran outside court, and you could see Stormy Daniels smiling on the side of the courtroom in the back, a little bit after this happened."
