Sen. Bernie Sanders: Donald Trump Jr.'s emails not 'politics as usual' Sanders said there is evidence of the possibility of collusion.

 -- Sen. Bernie Sanders told "The View" that Donald Trump Jr.'s emails are not a part of "politics as usual" and "we have some very strong evidence" of possible collusion in the Russia probe.

Sanders said that while "politics is ugly" and "there is ... effort to try to destroy candidates personally," he believes Donald Trump Jr.'s 2016 emails with Rob Goldstone are not "politics as usual."

"Presidential candidates do not have emails chains with foreign governments who are talking about how they can elect you and have dirt on your opponent," Sanders said. "That is a clear violation of campaign finance law."

"It is not true that this is politics as usual," Sanders continued. "This is very, very unusual. And that is why these investigations are taking place."

Sanders did not say mounting evidence in the Russia probe showed a smoking gun, but that there is "very strong evidence about the possibility of collusion."

He said focus should be placed on Americans' trust in the investigation.

"What is important is that every American, whether they're conservative or progressive, you like Trump, you don't like Trump — that they believe this process is objective and it is fair. That it is methodical," Sanders said.

"Let the process continue," Sanders continued. "We'll reach judgment after the evidence is accumulated."
