In one instance prosecutors pointed to, Papadopoulos tweeted from his public Twitter account that the FBI’s investigation was “the biggest case of entrapment!” The next day, Papadopoulos said he was considering withdrawing his guilty plea because he believed he was framed.

Several days later, he tweeted that he had been sentenced “while having exculpatory evidence hidden from me.”
