Of course evidence is needed before anyone is impeached or charged with treason. I think what we're all saying here is that it seems likely Trump has done some very wrong stuff in regards to his coziness with Russia. You know, where there's smoke there's fire… it just seems that given what we've heard so far, and what we know of Trump's character, that it is far more likely Trump connived with Russia to interfere in the election or is at the least beholden to Russian interests that would render him unfit to continue as President.
