"President Trump boasted about highly classified intelligence in a meeting with the Russian foreign minister and ambassador last week, providing details that could expose the source of the information and the manner in which it was collected, a current and a former American government official said Monday. The intelligence disclosed by Mr. Trump in a meeting with Sergey V. Lavrov, the Russian foreign minister, and Sergey I. Kislyak, the Russian ambassador to the United States, was about an Islamic State plot, according to the officials. A foreign ally that closely guards its own secrets provided the information, which was considered so sensitive that American officials did not share it widely within the United States government or pass it on to other allies."
