“What in God’s name made Trump think it would be a good idea to ask to bring Russia back to the table?” the FBI agent told Insider. “How does this serve US national-security interests?”…

A former senior Justice Department official, who worked closely with the former special counsel Robert Mueller when he was FBI director, didn’t mince words when reacting to Trump’s performance at the G7 summit: “We have a Russian asset sitting in the Oval Office.”

Glenn Carle, a former CIA covert operative and frequent Trump critic, told Insider there’s been “no question” in his mind for years that the president is behaving like “a spy for the Russians.”
