(J. Scott Applewhite/Associated Press)If confirmed, legal scholars say collaboration between Flynn and Mueller would be the biggest news in the Trump-Russia probe so far. George Papadopolous, former foreign policy adviser with the 2016 Trump campaign, is now a co-operating witness in special counsel Mueller's Russia investigation. Which is why legal experts suggest that Flynn's legal split from working with Trump's lawyers likely means Flynn is now working with Mueller. A month after the message from Trump, Flynn refused to hand over documents subpoenaed by a Senate panel. 9/ Trump's legal exposure comes in part from an April call to Flynn in which he told him to "stay strong"—after which Flynn refused to hand over docs to Congress.
