Former Deputy Attorney General Rod Rosenstein authorized the release to the media of text messages between two highly placed FBI employees who exchanged criticism of then-candidate Donald Trump during the 2016 presidential campaign, the Justice Department has revealed in a new court filing.

Rosenstein also said in the court filing submitted shortly before midnight Friday that he made the decision to share the messages with the press in part to protect FBI agent Peter Strzok and FBI attorney Lisa Page from the drip effect of incremental releases of the texts by lawmakers or others.
