WASHINGTON -- As part of a plea deal, former national security adviser Michael Flynn has admitted that a senior member of the Trump transition team directed him to make contact with Russian officials in December 2016.

Flynn pleaded guilty Friday to making false statements to the FBI, becoming the first official who worked in the Trump White House to make a guilty plea so far in a wide-ranging investigation led by special counsel Robert Mueller into possible coordination between Russia and the Trump campaign to influence the outcome of the 2016 election.

The government did not reveal the identity of the senior transition official.

Flynn didn't speak in court, other than to say he would plead guilty.

White House lawyer Ty Cobb says “nothing” about Flynn guilty plea implicates anyone in the Trump White House.
