Late March 2016: Mifsud introduces Papadopoulos to "Putin's niece" (not actually Putin's niece)
Late March: Papadopoulos, in a meeting with Trump, Sessions and others, says he can connect the Trump campaign with the Putin campaign. Sessions vehemently does not remember this.

Late April: Mifsud tells Papadopoulos that Russia has thousands of DNC emails, a fact not known to the DNC, the FBI, or the CIA
