Federal prosecutors sorting through materials seized from Michael Cohen, President Donald Trump’s personal attorney, said Wednesday they needed more time to piece together the contents of a shredder taken in an FBI raid.

At a court hearing in New York, prosecutors told U.S. District Judge Kimba Wood that they’d turned over most of the materials seized during the April 9 raids of Cohen’s office and Park Avenue hotel room to Cohen’s legal team, with the exception of two BlackBerry devices and the shredded documents.
