Lt. Gen. Michael Flynn, President Donald Trump’s former national security adviser, has reached a plea deal over lying to the FBI about his back channel conversations with the Russian Ambassador Sergey Kislyak, ABC News reports. 
He’s set to enter a plea in U.S. District Court on Friday at 10:30 a.m.
A brief statement released by Mueller’s team Friday morning does not say what information Flynn has provided the government as part of this deal, but sources familiar with the agreement told ABC News Friday he has made a decision to assist investigators.
The Washington Post reports: 
The charge relates to false statements Flynn made to the FBI on January 24, four days after President Trump was inaugurated, about his meeting with Kislyak during the transition.
Flynn is accused of making false statements to the FBI about asking the ambassador in late December to “refrain from escalating the situation in response to sanctions that the United States had imposed against Russia that same day.” Flynn also told authorities he did not recall the ambassador saying the Russians would moderate their response to Obama administration sanctions after the conversation.
Separately, authorities say Flynn lied about asking the ambassador to delay a vote on United Nations Security Council resolutions.
