[Congress] need[s] to reopen the hearings
I read and feel your indignation, however, I see no political or legal remedy for either real or perceived "crimes".
It doesn't appear to be illegal for anyone running for office to be engaged in business activities. It is not a crime to lie to the press or ones supporters about those activities. In fact his supporters have told many reporters many times they do not care if he lies. Apparently his elected supporters in Congress agree.
So I have to ask, how would your indignation be assuaged in a highly polarized political world?
