After a special counsel declined to take a stand on whether President Donald Trump had committed obstruction of justice in the Russia investigation, Attorney General William Barr decided there was not sufficient evidence that he had.

The decision by Barr and Deputy Attorney General Rod Rosenstein sprang from a comprehensive report prepared by Robert Mueller on his now-concluded investigation. While that report has not been made public, a summary Barr sent to Congress said “most” of the evidence on obstruction has “been the subject of public reporting.”

A senior Justice Department official confirmed to TIME that most of the evidence is already known from news reports.

“That’s a significant line and that was put there intentionally,” the official said. “You all know basically almost as much as we do.”
