According to Washington Post story, President Trump revealed code-word intelligence about ISIS during a meeting with Russia’s Ambassador and Foreign Minister
Washington (May 15, 2017) – Senator Edward J. Markey (D-Mass.), a member of the Senate Foreign Relations Committee, issued a statement sharply rebuking President Trump based on allegations in a story in The Washington Post that he revealed highly sensitive classified material to senior Russian officials during a meeting last week. According to the media story, President Trump reportedly revealed information about ISIS that could compromise a partner country’s key intelligence sources, and enable Russia to “identify our sources or techniques” for gathering intelligence. According to the story, the information that President Trump revealed was so sensitive that the United States had previously refrained from sharing it even with allies. 
“President Trump’s decision to relay some of our most sensitive intelligence with representatives of the Russian government betrays an astounding lack of judgment. By revealing ‘code-word’ information to Russia, President Trump may have compromised key intelligence sources, endangered the fight against ISIS, and undermined the trust of our international partners. Congress must immediately investigate this irresponsible action and take steps to ensure that Trump does no additional damage to U.S. national security in his dealings with Russia. 
“While the President may have the authority to declassify U.S. intelligence, it is imperative to the safety of our military and intelligence personnel, and those of our partners, that he do so through a careful and deliberative process. There is no evidence that Donald Trump did that.”
