Who is George Papadopoulos, first to be sentenced in Russian investigation?

George Papadopoulos, who briefly served as a foreign policy adviser to President Donald Trump’s campaign, will be sentenced Friday for lying to the FBI.

Papadopoulos, 31, pleaded guilty Oct. 5, 2017, to lying about connections to people he understood were connected to the Russian government. Prosecutors say Papadopoulos had hoped to broker deals between the campaign and Russian officials.

Papadopoulos was arrested at Washington Dulles International Airport on July 27, 2017, and arraigned the next day, charged with lying to the FBI, among other charges.

Papadopoulos’ guilty plea in October 2017 was part of a plea bargain with prosecutors from special counsel Robert Mueller’s investigation into Russian meddling in the U.S. presidential election.
