The key here is that, before Papadopoulos has even begun work for the Trump campaign--but is known to be joining it--these Deep State operatives with FBI links begin trying to feed him with talk about Russia and potential Trump/Putin meetings. Once Papadopoulos had begun work with the Trump campaign, this morphed into talk of collusion and Russia possessing Hillary Clinton emails, with Papadopoulos being contacted by intel officials from multiple Five Eyes countries: the US, UK, Australia--hot and heavy.
Listen to the whole interview. Bartiromo brings up the issue that Barr has mentioned several times--the whole question of what predication, if any, there actually was for the targetting of Trump through his campaign associates. Toward the end Papadopoulos makes some excellent comments regarding the way he was set up and framed and draws parallels to the experience of Michael Flynn. I strongly suspect we haven't heard the last of that.
