WASHINGTON - US Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, said allegations that President Donald Trump released classified information to Russia would be a 'slap in the face' to the US intelligence community, if true. 'Risking sources & methods is inexcusable, particularly with the Russians,' Warner said in a comment on Twitter and distributed by his office, referring to a Washington Post report that Trump disclosed classified information to Russia's foreign minister during a meeting last week.
