The search warrant, while heavily redacted, offered new details about the federal inquiry of Cohen's business dealings and the FBI raids of his Manhattan home and office. That's one of the most surprising revelations from the nearly 900 pages of search warrant materials in the Cohen case made public on Tuesday.
Through warrants for Cohen's home, office, hotel room, iPhones, bank safety deposit box, email accounts, and more, prosecutors built their case over some nine months.
The release provides extensive detail about Cohen's financial crimes, but a section detailing Cohen's campaign finance violations is completely redacted. Cohen implicated Trump in his guilty plea, saying the president directed him to make the payments during his 2016 campaign.
Cohen cooperated - partially - with federal prosecutors in NY, as well as with Mueller, in hopes of reducing the amount of prison time he would have to serve.
Michael Cohen recently testified before Congress that Trump continued discussing a possible hotel deal in Russian Federation through the first half of 2016. The documents also revealed that Robert Mueller's team were granted permission to review years of Michael Cohen's emails and online data during his time working for Donald Trump.
What are these documents exactly?
The FBI raided Cohen's Manhattan home and office last April, marking the first public sign of a criminal investigation that has threatened Trump's presidency and netted Cohen a three-year prison sentence for tax evasion and campaign-finance violations.
The warrants show that federal agents sought information from Cohen's Gmail account, as well as an account he set up for his legal and consulting work.
The special counsel was granted a second warrant for "content stored in the iCloud account" associated with Cohen's Apple ID in August 2017.
November 13, 2017: The FBI successfully sought to broaden the timeline of the Cohen Gmail account emails it was seizing, asking for all message sent and received between June 1, 2015 and November 13, 2017. Some of those payments were from companies with strong foreign ties, including a Korean aerospace company and Columbus Nova, an investment management firm affiliated with Russian billionaire Viktor Vekselberg.
February 8, 2018: The special counsel "referred certain aspects of its investigation into Cohen" to the Manhattan U.S. Attorney's office, "which is working with the FBI's NY field office".
In an April 2018 affidavit, the Federal Bureau of Investigation agent argued that "providers are required to disclose data even if it is stored abroad" under the new law.
Cohen has provided information to investigators about Trump and the Trump campaign, but prosecutors said he refused to tell them everything he knew.
