"It was extremely limited".
"What the Clinton campaign did, what the DNC did was actually exchange money, they took a meeting", Sanders said.
The White House has acknowledged this one meeting as there is photographic evidence of it from Trump's own Instagram account (Papadopoulos is third from left). And he was part of a list that was read out in the Washington Post.
Additionally, Sanders' repetition of the word "volunteer" to show reduced significance rings hollow in light of the fact Manafort also worked on the campaign for free and is now accused of, amongst other things, "conspiracy against the US".
But the bigger story came later yesterday when it was revealed that former policy adviser George Papadopoulos had pleaded guilty to lying to the FBI during the Russian investigation.
She replied: "There are thousands of photographs [of Trump] with millions of people".
She said Trump hasn't changed his principles on a tax overhaul.
"When you compare those two, it's like apples and oranges".
She was responding to a volley of questions on the surrender of Paul Manafort, Trump's former campaign manager, who has been indicted on 12 counts by a special counsel investigating into alleged Russian interference into last year's presidential elections.
Papadopoulos was living in London when he joined the campaign, according to the indictment.
Mr. Papadopoulos's offers were repeatedly rebuffed by the campaign, although one official told him to go to Russian Federation in order to gather dirt about Democratic nominee Hillary Clinton.
According to court documents, Papadopolous' false statements to the Federal Bureau of Investigation concerned his contact with a professor with connections to the Russian government about "thousands of emails" that could damage Hillary Clinton.
Sanders said she was not aware of the specific individuals, but she believes he is an example of somebody doing the wrong thing, while the Trump campaign did the right thing by voluntarily turning over emails to special counsel Robert Mueller, an action that ultimately led to Papadopoulos' arrest and guilty plea.
A Trump campaign supervisor encouraged Papadopoulos to make the trip "if it is feasible" on August 15, 2016.
