 Today, prosecutors acknowledged publicly for the first time Friday that they seized records this week from Cohen. 
 
 The revelation came as Cohen and Trump sought a court order barring federal prosecutors from accessing the records they took during raids on his home and office Monday morning. 
 
 Lawyers for Cohen and Trump, neither of whom was present in court, argue that at least some of the records are subject to attorney-client privilege and should not be viewed by prosecutors until they, or an independent third party appointed by the court, have a chance to review the material. 
 
 Cohen "applied [Thursday] evening for an opportunity to take the first cut" at determining whether the documents are privileged or relevant to the investigation, Judge Kimba Wood said. "Both parties recognize the search of an attorney's devices and offices are subject to special consideration."

 A hearing Friday in Manhattan federal court was put on hold until Monday after an attorney for Trump intervened and requested additional time. 
 
 "He as an acute interest in these proceedings," said Joanna Hendon, an attorney for the president who said she was hired Wednesday night. 
 
 Hendon noted the "exceptional nature" of her client and expressed concern about the prosecutors' internal "taint team" that separates evidence that is privileged from evidence that is available for prosecutors to view. 
 
 "We don't need to rush," Hendon said. "There is an appearance of fairness problem." 
 
 A taint team is a group of people who help determine what falls under attorney-client privilege and should not be shared with investigators. It's standard when searching a lawyer's office. 
 
 “The government’s use of a filter team appropriately protects applicable privileges," the court documents obtained by ABC News state. 
 
 Monday’s search was broader than previously reported: in addition to Cohen's home and office, there were court-authorized searches of a safety deposit box and two cellphones. 
 
 Cohen “is being investigated for criminal conduct that largely centers on his personal business dealings,” according to court documents. 
 
 The federal prosecutor’s office “has already obtained search warrants -- covert until this point -- on multiple different email accounts maintained by Cohen, and has conducted a privilege review of the materials obtained pursuant to those warrants,” the court documents state. 
 
 That review, prosecutors said, showed that Cohen "is in fact performing little to no legal work and that zero emails were exchanged with President Trump." 
 
 Cohen has not been charged with anything. He has not responded to news he is under investigation, declining to comment when contacted by ABC News.

 Thomas McKay, one of the prosecutors handling the case, said the president's attorney-client privileges are no different than anyone else's. He accused the president and Cohen of delay tactics but promised prosecutors would not view any of the seized material until the judge makes her ruling following the hearing on Monday. 
 
 Also at issue was how much of this dispute will happen in open court. News organizations objected to parts of the hearing -- originally scheduled without notice -- taking place outside of public earshot. 
 
 “I don’t take this position lightly,” said Wood. 
 
 Rachel Strom, an attorney for ABC News, successfully argued to keep most of the hearing open to the public. 
 
 "This is the most important hearing that’s happening today and the public has a right to know how the court is going to handle the search of the president’s lawyer’s documents," Strom said. ||||| Michael Cohen, President Donald Trump’s longtime confidant and former personal attorney, is likely to cooperate with federal investigators, as his lawyers are expected to leave the case, sources said.

 To date, Cohen has been represented by Stephen Ryan and Todd Harrison of the Washington and New York firm, McDermott, Will & Emery LLP, but a source representing this matter has disclosed to ABC News that they are not expected to represent him going forward. Ryan declined to comment. 
 
 A source familiar with the matter tells ABC News that among the reasons for Cohen’s change in counsel is a fee dispute. 
 
 No replacement counsel has been identified as of this time. 
 
 Cohen, who has been under criminal investigation for months, which is separate from the special counsel case, has been rushing to meet U.S. District Court for the Southern District of New York Judge Kimba Wood’s Friday deadline to complete a privilege review of over 3.7 million documents seized in the April 9 raids of Cohen’s New York properties and law office. 
 
 Representatives from the Southern District of New York declined to comment. 
 
 Cohen, who is under federal investigation now with no legal representation, is likely to cooperate with federal prosecutors in Manhattan, sources said. This development, which is believed to be imminent, will likely hit the White House, family members, staffers and counsels hard.

 Two sources who are familiar with a warrant in the case told ABC News in April that federal agents were hunting for records tied to Cohen’s personal business dealings and secret deals with Trump's alleged mistresses, media organizations and the 2016 presidential campaign. 
 
 Cohen’s attorney at the time of the raids released a terse statement shortly after the April raids arguing that the seized documents included “the unnecessary seizure of protected attorney-client communications between a lawyer and his clients.” 
 
 “These government tactics are also wrong because Mr. Cohen has cooperated completely with all government entities,” Stephen Ryan said. 
 
 Two days after the raids, Cohen told ABC News: “I just want my stuff back.” 
 
 President Trump also lashed out in a tweet, writing, “Attorney-client privilege is dead!” 
 
 He told reporters at the White House that the move against his longtime personal attorney, which he likened to a break-in, was a “disgraceful situation.” 
 
 “It’s an attack on our country in a true sense. It’s an attack on all we stand for,” the president said during a meeting with senior military leadership at the White House. “That is really now on a whole new level of unfairness.” 
 
 Cohen then went to federal court in Manhattan arguing that his attorneys should be given a first look at the materials seized in the raids for items potentially covered by attorney-client privilege before federal prosecutors could examine the haul.

 Judge Wood subsequently appointed former federal judge Barbara Jones to act as a “special master” to conduct an impartial review of the materials and to referee any disputes between Cohen and the government. 
 
 Trump and the Trump Organization intervened in the case and were also granted access to review the materials for potentially privileged items. 
 
 Jones reported last week that of the first 300,000 items reviewed, she had determined that just 162 of them were covered by attorney-client privilege. She rejected three items that Cohen, Trump or the Trump organization had designated as privileged. 
 
 Judge Wood has given Cohen’s attorneys until Friday to complete the review of the remaining documents. Any remaining items to be reviewed would be turned over to a team of federal prosecutors unconnected to the case to complete the examination of the documents. 
 
 ABC News' James Hill, John Santucci, Katherine Faulders and Kyra Phillips contributed to this report.
– Trump attorney Michael Cohen is indeed under criminal investigation. That might not be a huge shock given that FBI agents raided his office earlier this week, but the Justice Department revealed that fact for the first time in a court document Friday, reports CNN. Cohen “is being investigated for criminal conduct that largely centers on his personal business dealings,” according to the document, though any further details were redacted. Another nugget: The raid turned out to be more extensive than thought, reports ABC News, with agents also searching a safety deposit box and two cellphones, in addition to Cohen's home and office. All of this came to light as part of a legal fight related to the raid. Attorneys for Cohen and President Trump want to block federal prosecutors from the seized documents until it can be properly determined if any should be shielded by attorney-client privilege. Friday's hearing in Manhattan was pushed into Monday when an attorney hired Wednesday by Trump, Joanna Herndon, requested more time. "He has an acute interest in these proceedings," she said of the president.
