imagine someone breaks into a bank. they use special saw to cut through the safe. we found that saw as they were using it. >> you caught them in action? >> we did. >> myers says the cyberattacks began with russian backed hackers. fancy bear and cozy bear. the information they obtained was passed on to wic likes and others to make public. the hackers also gained access to some republican files, but that information never be cam public. even after being exposed, the hacks against democrats >> this is pretty bold. pretty brazen, in a lot of ways. >> very russian. >> what do you moon by that? >> don't think the russians are shy or would pull back after something like that happens. they're doing their thing. >> reporter: one reason the cia believes russia was frying to tip the scales to trump, they have used similar tactics to favor candidates before recently in elections in ukraine. scott, no within is saying the actual vote count in the u.s. was hacked. >> our homeland security correspondent, jeff pegues, thank you. the president-elect is not buying any of this and he has picked a fight with the cia. here is our chief white house correspondent, major garrett. >> reporter: i

spy agencies. >> i do. >> today on twitter, mr. trump lashed out at democrats. can you imagine if the election result were opposite and we tried to play the russia cia card? intelligence community concluded in october that russia directed the rerecent compromises of e-mails almost universally himaging to democrats and llary clinton. throughout the campaign, mr. trump resisted. >> she has no idea whether it is russia, china or anybody else. >> i am not quoting myself. >> if it is russia, nobody knows, it's probably china. >> could be somebody sitting on their bed that weighs 400 pound. okay. >> in july, candidate trump. egged on russian hackers to find deleted clinton e-mails. >> russia, if you are listening, i hope you're able to find the 30,000 e-mails that are missing. >> mr.

conference twice. stay tuned after the new year. >> thank you, for insight we spoke late today with republican william cohen, former senator of maine and secretary of defense in the clinton administration. >> i think it is a big mistake to belittle the intelligence community because it looks as if you are trying to politicize it. if the intelligence community agrees with me, they're good. if they don't, they're bad. and i think the notion that somehow this is the same group that said there were nook leer weapons in iraq misses the point. like saying if -- if donald trump has filed seven bankruptcies, several of his companies, does that mean heap is a bad businessman. he made good choices, bad choices. some times the community gets it wrong. most of the time they get it right. >> mr. trump said that he was quote "a smart person" and therefore he didn't need to receive the presidential intelligence brief every day. what do you think of that? >> i think information is power. and -- information doesn't always translate into knowledge. but at least you have the basic facts in front of you. i think it is important the president be aware of what is taking place on a global basis every day and not every week. >> so your advice to the president elect would be what? >> listen more. read more. you have the intelligence community among the finest in the world listen to what their analysis its and recommendations to you are. >> one of the complaints he appears to have the president's daily brief has a lot of redundant information day after day. >> the president can say, simplify this because i know all of the other material, but i want it in five, not ten pages. he can do that. but i think to ignore the daily briefing is, is not wise. >> former defense secretary, william cohen. thank you for being >> a pleasure to for its part, the fbi has not concluded its investigation into this, but so far it is not siding with the cia on the motive for the 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 an aggressor that consistently undermines american interests. he said the intelligence committees are and should be looking into it. >> this is serious stuff. >> democrats, led by new york's chuck schumer are pushing for a separate congressional investigation into russia's election meddling. >> we need how to get to the bottom of this in a fair, nonpartisan, nonfinger pointing way. >> schumer appeared on cbs this morning with arizona republican john mccann who agrees with him. >> there is no that russians and others have, have hacked. there is no doubt about that. now the question is the intention. >> reporter: ten members of the electoral college want their own briefing about donald trump's connection to russia. so far, the director of national intelligence has had no comment. >>
