>The New York Times reported earlier this month that the FBI’s attention was initially drawn to the Trump campaign’s contacts with Russia not by the dossier, but by a representative of Australia’s government who had met with then-Trump campaign staffer Papadopoulos. Papadopoulos, who has since pleaded guilty to charges of making false statements to the FBI, told the diplomat that Russia had political dirt on Trump's campaign rival, Hillary Clinton.
It appears that Australia is tied into the Trump/Russia collusion "investigation."
