This meeting appears to be a set up by Clinton, Fusion GPS and others.
Fusion GPS met with lawyer before and after the meeting and organized the sting. Who knows what they planned and how they tried to entrap Trump JR.
Sounds like one more slimy Clinton operation.
Clinton and DNC paid for the phony dossier on Trump and since Donna Brazile revealed Clinton's secret agreement to control the coffers for the DNC, that means it's collusion by Clinton and Obama with the Russians to thwart the election - exactly what they're accusing Trump of! They try to set Don Jr. up but Trump campaign didn't take the bait, yet Clinton paid for her's & gave it to McCain and the press, while the meeting served the purpose for getting the FISA warrant so they could monitor and unmask Trump campaign. Simpson clearly perjured himself to FBI and to Mueller + his grand jury. Veselnitskaya has now just changed her story as well (good timeline of recent events
here). This puts any meeting between Trump & Putin in Vietnam in very interesting context.
