Michael Flynn pleads guilty to lying to FBI in Russia probe

President Donald Trump's former national security adviser, Michael Flynn, pleaded guilty Friday to "willfully and knowingly" lying to the FBI in Special Counsel Robert Mueller's investigation into possible Russian interference in the 2016 election.

Flynn lied to investigators in January about conversations he had in December 2016 with Russia’s ambassador to the U.S., Sergey Kislyak, according to court documents released Friday.
