system all morning long for us. The Russia investigation now and new questions about what former national security adviser Michael Flynn's plea deal with the special counsel will mean for president trump. The president attacking the FBI on Twitter over the weekend, our senior justice correspondent Pierre Thomas has more and joins us from Washington. Good morning, Pierre. Reporter: Robin, good morning. Flynn's guilty plea and pledge to cooperate with the special counsel is creating intense drama here in Washington with many wondering what he's going to say and who if anyone he might implicate.
