russian hacking. and here on capitol hill, there were new calls today for another investigation to get to the bottom of it. here is congressional correspondent nancy cordes. >> the russians are not our friend. >> republicans found themselves caught between distrust of putin and allegiance to mr. trump. mitch mcconnell tried to put it gentle as possible. >> i addressed how i feel about the russians. and i help that those who are going to be in positions of responsibility in the new administration share my view. >> house speaker paul ryan warned that under president putin russia has been
