UPDATE [12/1/17, 11:40 a.m. ET]:
Flynn officially pleaded guilty to making false statements to the FBI, according to CNN.
Following his plea, Flynn issued a statement acknowledging wrongdoing but describing accusations that he committed “treason” as “false”:
Former National Security Advisor Michael Flynn will reportedly plead guilty Friday to special counsel Robert Mueller's charge he lied to the FBI about his conversation with a Russian ambassador after the 2016 presidential campaign.
Mueller accused Flynn of “willfully and knowingly” making “false, fictitious, and fraudulent statements,” according to CNN. Flynn, apparently cooperating with the Russia probe, will appear in a federal court at 10:30 a.m. ET on Friday, The New York Times reported.
While Mueller has brought charges against members of President Donald Trump's campaign, Flynn is the first administration official to face charges. Speculation emerged recently that Mueller might offer Flynn a plea deal, apparently signaled after Flynn's attorney stopped sharing information with Trump's lawyers.
Mueller's team reportedly interviewed White House adviser Jared Kushner earlier in November to see whether Kushner had any exonerating information on Flynn.
At the end of October, Mueller indicted Trump's former campaign manager, Paul Manafort, along with his former business associate, Rick Gates, on 12 counts, including conspiracy against the United States.
