I'm just pointing out what exactly happened.
Even the NY Times admits:
"Among the details the president shared was the city in Syria where the ally picked up information about the plot, though Mr. Trump is not believed to have disclosed that the intelligence came from a Middle Eastern ally or precisely how it was gathered."

So where did all that extra information come from? If the leaker was so concerned that Trump told the Russians about this ISIS-held Syrian city (which there aren't many left and most likely Raqqa), why provide so much more information to the media?
