A judge approved searches of Cohen's Park Avenue apartment, downtown Manhattan office, a safe deposit box, hotel room and two Apple iPhones - leading to Federal Bureau of Investigation raids that received significant media coverage previous year.
We put together a timeline based on the newly unsealed documents to show exactly how the Cohen investigation came together. In them, officials in the Southern District of NY laid out their suspicions about Cohen, how they planned to investigate and why those warrants were needed.
U.S. District Judge William H. Pauley III said redacted versions of the documents should be released Tuesday.
July 18, 2017: Federal Bureau of Investigation agents sought and obtained a search warrant from U.S. District Judge Beryl Howell in Washington, D.C., for all emails sent or received from Cohen's Gmail account between January 1, 2016 and July 18, 2017.
Although the documents could reveal more information on the case, they are unlikely to provide many new details about the campaign finance violation to which Cohen pleaded guilty that stem from payoffs he made to women who alleged they had affairs with Trump prior to the 2016 election.
Among them, the bank account Cohen used for the hush money payment to Stormy Daniels "received substantial payments from foreign sources", the Federal Bureau of Investigation said, according to reports in the Daily Mail and Courthouse News.
That period included the first few months of Trump's presidency, as well as much of the 2016 campaign.
They detailed how investigators believed money going to Cohen, including to his firm Essential Consultants, was for political consulting, including from worldwide clients with issues pending before the Trump administration.
The FBI said there had been "probable cause" to believe Cohen had committed campaign finance violations and it received a warrant for emails sent and received between June 2015 and February 2018, according to court documents.
Trump's former personal lawyer and "fixer" also kept the income hidden from two banks with which he was renegotiating payments on $20 million in loans for the purchase of 32 taxi medallions after their value plummeted due to competition from Uber and other ride-hailing services, the court papers say.
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.
■ Investigators looked closely at Cohen's campaign finance violations, and details of what they found are still being withheld.
