Papadopoulos sent the Trump Campaign several emails describing his Russian outreach. On Apr 10, Papadopoulos emailed who he thought was Putin’s niece who responded “would be very pleased to support your initiatives between our two countries.” Papadopoulos responded asking for a foreign policy trip to Russia. She responded with “This is already been agreed” and “…we are all very excited by the possibility of a good relationship with Mr. Trump. The Russian Federation would love to welcome him once his candidature would be officially announced.” There is much more like this, read the Stipulation. See Papadopoulos Timeline.
