re: Why is so terrifying and horrible that people Trump knows talked to Russia?

For starters, Trump and his minions denied it when they knew it was happening, and secondly, there are very real concerns about whether or not the Trump people colluded with the Russians' interference in the American election. The fact that the Russians did interfere in the election is beyond dispute, according to five intelligence agencies. The big question is to what extent the Trump campaign colluded with them. The only way the American public will know for sure is if there is an independent investigation in the matter. It would stand to reason that the American public has a right to know answers to this question. The early signs though point to a Republican cover-up of the matter, so they will probably behave as the rank hypocrites that they are. They didn't have a problem spending more time investigating Hillary Clinton than Congress did investigating 9/11, Pearl Harbor or Watergate, so why can't they do their damn job and get to the bottom of Trump's ties to Russia in a way that the public can fully understand them? Hell, they won't even make that lying, Russian dick-sucking Trump release his tax returns.
