Prosecutor Andrew Weissmann’s forthcoming book about his role in the Mueller investigation will have a clearer path to publication than many others dealing with with the Trump administration.

Random House said that Weissmann’s book, Where Law Ends: Inside the Mueller Investigation, has already been approved by the Department of Justice, CNN reports. The department didn’t comment on the book to the news network.

Weissmann was a member of special counsel Robert Mueller’s team of lawyers who investigated Russian interference in the 2016 election. Random House announced Monday that it would be publishing his book, which it describes as “a story about a team of public servants, dedicated to the rule of law, tasked with investigating a president who did everything he could to stand in their way.”

Weissmann said he thought it was “necessary” to write a book about the investigation, the Associated Press reports.

“I am deeply proud of the work we did and of the unprecedented number of people we indicted and convicted—and in record speed,” he said. “But the hard truth is that we made mistakes. We could have done more. Where Law Ends documents the choices we made, good and bad, for all to see and judge and learn from.”

Where Law Ends is slated for publication on Sept. 29.
