From a Wall Street Journal story by Corinne Ramey and Jeffrey A. Trachtenberg headlined “Ex-Trump Prosecutor’s Book Draws Warning From Manhattan District Attorney”:

The Manhattan district attorney’s office said that a forthcoming book by a former top prosecutor could compromise its continuing investigation of former President Donald Trump, warning that the author could be unlawfully using confidential information for his personal advantage.

“Based on the pre-publication descriptions of his book and the benefit of current knowledge of the matter, but without access to the manuscript, this office believes there is a meaningful risk that the publication will materially prejudice ongoing criminal investigations and related adjudicative proceedings,” the office’s general counsel, Leslie Dubeck, said in a letter to the publisher, Simon & Schuster.
