The report says that in May 2016 George Papadopoulos told Australia's top diplomat in Britain about the emails during a night of drinking. Two months later, when the stolen emails appeared on the Internet, the Australian officials passed the information provided by Papadopoulos to the USA colleagues, which served as a driver of the investigation' launch by the FBI into Moscow's alleged interference in the U.S. presidential election.
The news appears to add to the number of pieces of intelligence, separate from a dossier compiled by a former British spy about Trump-Russia ties, that raised concerns among United States national security officials and propelled an investigation.
George Papadopoulos reportedly told Alexander Downer that Russian Federation had dirt on Hillary Clinton. President Donald Trump and his allies have dismissed the investigation as a Democratic " witch hunt " spurred by a dossier, which was compiled by former MI6 officer Christopher Steele, and alleges a number of explosive Trump-Russia ties.
The tip was enough to prompt the FBI to launch an investigation into possible collusion between Trump's campaign and Russian Federation to undermine Hillary Clinton.
The FBI caught wind of Papadopoulos' claims more than two months after the London meeting with Downer. Back then he was an "excellent guy", but after he pleaded guilty to a charge of lying to the Federal Bureau of Investigation earlier this year he was immediately derided by Trumpies as a mere "coffee boy" that nobody took seriously.
He is the current champion of anti-Trump supporters and American liberals, but Alexander Downer's elevation to worldwide hero may prove more than amusing for many Australians.
Mr Trump was inaugurated as 45th USA president in January this year.
Papadopoulos' knowledge of Russians possessing stolen emails from Democrats "leads to all sorts of questions such as who else on Trump campaign knew, what did the Trump campaign do with this information", Lieu said.
That conversation reportedly happened in a bar in May 2016.
"And we all need to let Mr. Mueller do his job".
Mr Papadopoulos worked as a foreign policy advisor for Mr Trump during his 2016 presidential campaign.
Court documents unsealed two months ago show in April 2016 he met with Joseph Mifsud, a professor in London who he believed to have substantial connections in the Russian Government and who claimed to have "thousands of emails" that would hurt Democratic presidential candidate Hillary Clinton. And Papadopoulos is cooperating with Mueller.
