O'Kay, O'Tink...this is smelling kinda fishy to me...couldn't open your link but I did find one from a Montana radio station...
"Brady Toensing of Burlington, the man responsible for the claims filed to the U.S. attorney for Vermont, was a chairman for the Trump campaign in his state." (My emphasis.)
And then,
"Sen. Sanders, formerly mayor of Burlington, Vermont's largest city, regards the claims as a political game levied against him after his run for president in the 2016 primary election, a platform which has transformed the small-state senator into an influential voice in American liberal politics."

So I am feeling a bit ho-hum, here...likewise just over the fence, in the probe into Russia interfering with the 2016 US Presidential election, I have been reading that countries ALWAYS are mucking into each others' elections, and the USA has done it to other countries zillions of times... ...so NOW, why are we suddenly probing?
