McMaster: "At no time, were intelligence sources or methods discussed. And the president did not disclose any military operations that were not already publicly known."
The Washington Post did not report that Trump discussed “sources or methods.”
The Washington Post actually said: "Trump disclosed information to Russia’s foreign minister and ambassador about the Islamic State, jeopardizing a critical source of intelligence on ISIS."
Trump revealed “code-word information” and “revealed more information to the Russian ambassador than we have shared with our allies,” said the Post.
It's not fake news because you disagree with it. It's fake news when it's deliberately meant to mislead you.
