Papadopoulos was interviewed by FBI agents on January 27, 2017, regarding any Trump campaign connections with Russia. After the interrogation, on the advice of his counsel, Papadopoulos deactivated his Facebook account, which contained correspondences with Russians, and created a new account.[82] On July 27, 2017, Papadopoulos was arrested upon landing at Washington-Dulles International Airport, placed in handcuffs and leg shackles, and put in a prison cell overnight for his arraignment the following day. He was released without bail and cooperated with Special Counsel Robert Mueller in his investigation.[63]On October 5, 2017, Papadopoulos pleaded guilty in the U.S. District Court for the District of Columbia to making false statements to FBI agents relating to contacts he had with agents of the Russian government while working for the Trump campaign.[83][48] The guilty plea was part of a plea bargain reflecting his cooperation with the Mueller investigation.[63] Papadopoulos's arrest and guilty plea became public on October 30, 2017, when court documents showing the guilty plea were unsealed.[84] Following his guilty plea, Trump described Papadopoulos as a "young, low-level volunteer named George, who has already proven to be a liar" and said few people in his campaign had heard about Papadopoulos.[85][86] FactCheck.org and PolitiFact, among others, noted that during the campaign, Trump, reading from a script, named Papadopoulos as one of his five foreign policy advisers—alongside Keith Kellogg, Carter Page, Walid Phares, and Joseph Schmitz—and described Papadopoulos as an "excellent guy".[87
