hacked into the dnc server in an effort to help donald trump be elected president. the e-mails forced debbie wasserman schultz to resign and the fbi is on the case. jan crawford has more. >> reporter: officials believe the hacking of the dnc went on more than ape year starting in june, 2015, a wave of cyberattacks into american political and government i institutions. the story didn't gain traction until wikileaks published e-mails embarrassing the democrats before the convention. >> if the republicans said that. they would say a conspiracy theory. donald trump hit back at democrats attempts to turn their new e-mail scandal into a problem for him. >> when the democrats say it, maybe trump stole everything from the dnc. aye, aye, aye, what a group we have. >> the clinton campaign is pointed to a so-called bromance with vladamir putin. something trump touted more than ape year. >> wouldn't it be nice if we actually did get along with russia. >> releasing the e-mails sort of a form of information warfare. >> "the new york times" national security correspondent, david sanger says intelligence agencies routinely collect information on political campaigns. but releasing those documents is unusual. >> it is clear russian actors were behind the attacks. seems clear it was probably two intelligence agencies. unclear what the political motive was. >> like many international business men, trump sought to curry favor with the russian government and courted russian investors for business ventures. trump projects in manhattan, phoenix, and fort lauderdale were financed with the help of the bayrock group started by a former soviet official. >> i never met putin in all fairness. but that put spin likes trump. therefore he went in and he stole it. he wants trump to win. okay. >> sanger says the timing is key to understanding the hackers motivations. >> it would seem unlikely though that influencing the election was the initial goal. because the first intrusion was in the summer of 2015. long before anybody knew that donald trump would emerge as the candidate. >> former u.s. intelligence analyst told abc news, the hack and like. looks like russians may be playing

mockery. shameful. cowardly. some of the polite terms to describe the ioc decision not to ban the entire russian team from the rio games. this is a decision that made nobody happy, except the russians. >> you know, you can't help realize the olympic flame is less bright to day that in was before. >> travis tigart, u.s. anti-doping agency chief is just one voice in an international chorus of criticism. but the truth is the olympic flame has been flickering for some time. particularly following the revelation that at the sochi games, the russians carried on elaborate state-run scheme to cover up illegal drug use by athletes. now the russian team, at least those who haven't previously failed a drug test will be allowed to complete in rio. the ioc punted. the various international sports governing bodies are asked to vet their own athletes to determine whether any should be banned in the way the iwaf has band, russian track & field team. it is unclear whether the federations have the resources or the will to do serious detective work in the less than two weeks before the rio games are due to open. the ioc president, thomas bach, decided not to confront vladamir putian on the grounds that clean athletes shouldn't be punished because of dirty ones. >> every human being is entitled to individual justice. >> but the international call for a ban is based on the fact that the russian olympic program has been tainted by the scheme. with the help of mos kwou security forces to swap, clean, urine samples for tainted ones. >> unfortunately, the russian federation and types at the top, with the ioc and the state of russia. are such, russia is essentially to big to be held accountable, as we would say, too big to fail. >> the ico policy is now being described as zero
