This is a joke...
This is what he actually said:
"Sanders told the Journal of his debate exchange on Clinton’s e-mails. “There’s an investigation going on right now. I did not say, ‘End the investigation.’ That’s silly. . . . Let the investigation proceed unimpeded.”"
So he said he thinks it is a red herring for the campaign at the moment as it gets away from actual real topics.
But he is saying no one should interfere with it either.
What do you think his answer should be? Sanders looks like a class act and way above the clown car idiots in the GOP race...
But no one wants to go near the Issue that Hillary Clinton has clearly the best record on Politifact on all candidates above 6%.
So every time you say Clinton lies you have to accept your asshat lies more...
