The congressional investigation into possible collusion between the Trump campaign and Russian hackers is nothing more than window dressing, employing only 9 staffers (this compared to 40 dedicated to the Benghazi investigation). Attorney General Jeff Sessions, a Trump appointed hatchet man, obviously has no interest or intention to investigate. The only viable investigation into Trump campaign's possible collusion with Russia WAS the one being headed by FBI Director Comey, now fired by the very object of his investigation.
If the Republicans in Congress don't immediately call for a special investigator and a FULL investigation, one can only assume that they are even willing to accept a treasonous president, as long as he is from their own party. The very foundation of our democracy is in the balance here. If the President gets away with this now, what will he try next.
