NBC reporter: Source says ISIS intel Trump discussed with Russians was nothing they didn't already know

The Post wrote that Trump’s disclosures “jeopardized a critical source of intelligence” on ISIS, and an official told the newspaper that he had revealed “code-word information” and was “more information to the Russian ambassador than we have shared with our own allies.”

Engel, however, wrote that an intelligence official told him it was Trump attempting to show the Russians “how cooperative he wants to be with them” in the fight against ISIS and it was “not new info.”
