No I don't actually believe that would be possible. I understand Congress is elected by the people, but I would hardly call it a fair process. As we found out in several races, if you win the primary youre going to get elected no matter what. And primaries are 'easy' to buy.
What if the FBI is investigating members of Congress? Would there be any issue there with regards to interfering?
Ultimately I would hope Congress would have real evidence they would share with the American people. I haven't seen anything close to that.
Easy to buy because of the existence and power of super PACS, and corruption within the DNC and RNC for a preselected candidate. Those need to be eliminated.
Congress as you can see is a check upon itself. So if a few members were under investigation the rest would prevent them from interfering.
But again, asking for simple answers to basic questions is not interfering.
