Federal prosecutors disclosed that they have reconstructed about 16 pages of shredded documents belonging to Michael Cohen, President Donald Trump’s longtime attorney who is under investigation by special counsel Robert Mueller.

In an update submitted Friday to U.S. District Court Judge Kimba Wood, who is presiding over the case, also revealed that “approximately 731 pages of messages, including call logs” were recovered from a BlackBerry phone found in the raids along with information from encrypted apps such as WhatsApp and Signal from newer phones.

The information found was turned over to Cohen’s attorneys to search for anything that could potentially be protected by attorney–client privilege or “highly personal information,” prosecutors said. Barbara Jones, the retired judge appointed by Wood to review information Cohen’s attorneys claim to be privileged, has thus far found less than one percent of documents to be privileged and unlikely to be used in the case against Cohen.

Wood previously set a June 15 deadline to finish evaluating seized documents for attorney–client privilege, but Jones requested Friday that the deadline be extended to June 25. Prosecutors also stated in their report that the FBI was still in the process of extracting data from another BlackBerry and could not predict how much information will be found.

Cohen is under investigation for alleged bank fraud, wire fraud and campaign finance violations. The FBI raided his home, hotel room and office in April in connection to the investigation.
