large enough to warrant the creation of a working group, made up of agents from the cia, fbi and nsa. >> having been involved in many counter intelligence cases in the past, i know what the russians try to do. they try to get individuals, including u.s. persons to act on their behalf, either wittingly or unwittingly. and frequently, individuals who go along a treasonous path do not realize they're on that path until it's too late. >> reporter: california democrat jackie spear. >> were you aware they were trying to cultivate then real estate developer donald trump for almost eight years? >> i'm not going to talk about any individuals. >> reporter: republicans like trey gowdy noted that contact alone was not proof of wrongdoing. >> did you see evidence of collusion, coordination, and russian state actors?

>> i saw information intelligence that was worthy of investigation by the bureau to determine whether or not such cooperation of conclusion was taking place. >> what was the nature of the information? >> as i said, mr. gowdy, i think this committee now has access to the type of information i'm alluding to here now. it's classified. and i'm happy to talk about it in a classified session. >> reporter: brennan revealed for the first time today that he reached out to his russian counterpart last year and said that russia would pay a price if it didn't stop trying to meddle in the u.s. election. scott, the russian officials denied the charges but they said they'd take his concerns to vladimir putin. >> nancy cordes on capitol hill. thanks. coming up next in manchester. the sobering truth about drinking and breast cancer. and later, we'll remember 007, sir roger moore.

their revered dictator, mao tse-tung. are we creating a new ai wei wei as we stand here? >> everybody can do it. >> reporter: easy? certainly not subtle, and maybe a little silly, but the chinese authorities took them very seriously. they thought it was subversive. why was the regime frightened of art? >> because they're afraid of freedom. and art is about freedom. >> reporter: they're afraid of freedom. >> yes. >> reporter: are you an artist? or are you an activist? >> i think i'm artist, and activist is the same thing. as artist, you're always an activist. >> reporter: you have to be political to be a good artist >> i think every art, if it's relevant, is political.

>> reporter: as a writer for "the new yorker" who spent years in beijing and chronicled ai wei wei's confrontations with the authorities, he called him an entrepreneur of provocation. what does that mean? >> it means that no matter what he's doing he's figuring out a way not to cooperate with the prevailing wisdom or the people in charge. and this can make a lot of people very angry. >> what's wrong with how things are to ai wei wei's mind? >> in china you are being constantly told that the world today is so much better than it was 20 or 30 or 40 years ago when chinese people were literally starving that you should be satisfied. and what ai wei wei is saying is absolutely not. you should demand more. >> reporter: it's not good enough to be rich. >> exactly. it's not good enough to be

>> to control the information, to limit the truth as most efficient tactics for a totalitarian society, for the rulers. >> reporter: he gathered the names of more than 5,000 dead children and published a list on the internet, shaming his government. and across china, people ook notice. there was a challenge to the government's authority. >> and they couldn't accept it. it was an act of radical transparency. nobody had ever done that before. and they didn't immediately know how to respond. they had never really encountered a person like ai wei wei. >> reporter: what were they worried that he might do? >> inspire people. inspire people to do and live the way that he did. >> reporter: the chinese authorities responded brutally, ai wei wei says police beat him up, and he later had to be hospitalized. doctors discovered bleeding in

his brain, which he says could have killed him. he documented it all on social media for his followers around the world. infuriating the government and escalating the confrontation. >> he weaponized social media. he figured out in a country that controls information so carefully that seizing the tools of information distribution is a very powerful thing to do. >> reporter: what did the chinese government think about that? >> they began to think he was a very dangerous person. >> reporter: ai wei wei was groomed to be a dissident since childhood. his father was a celebrated poet who was denounced as a traitor and exiled to the edge of china to the gobi desert, where ai wei wei watched his father's humiliation as he was forced to clean public toilets. you were an outsider from the beginning. >> yes, i'm a natural outsider. i've always been pushed out. but that also give me very special angle to look in a

sense. >> reporter: it made you an independent thinker. >> it made me an individual. and i always have to make my judgment independently, because the mainstream will never accept somebody like me. >> reporter: ai wei wei got out of china in the first opportunity and moved to new york in the '80s. he was intoxicated by the city, chronicling everything in pictures, gathering inspiration from andy warhol and gaining a living by doing street art. you were selling them for how much? >> 15? $15. >> reporter: some of his work now sells for millions, but in america he discovered something you can't put a miss on. you once said once you experienced freedom, it stays in your heart, is that true? >> it's true.

you taste the most important thing in life, and you will never forget it. >> reporter: after a decade in the u.s. he moved back to china and set up a studio in beijing, breaking new ground and challenging old sensibilities with mischievous art, with him destroying a 2,000 year old urn. i wants to shatter the official version of history. you smashed a priceless urn. >> it's not priceless. >> reporter: for a lot of chinese people, it's a priceless part of their history. >> for me to smash it is valuable act. >> reporter: if you buy that, and the art world certainly did. look what he did to these urns, doused in bright paint or emblazoned with the coca-cola logo, paying tribute to his

idol, andy warhol. by 2010, new commissions were rolling in, and ai wei wei's work was more ambitious. not all of it was political. he cast giant animal heads in bronze and sent them on tour around the world. he hired 1600 artisans to hand craft porcelain sunflower seeds. then carpeted the floor of a giant atrium in london with 100 million of them. it captivated the public. and helped turn ai wei wei into an art scene super star. you're the darling of the art world. >> i'm the darling of the art world, i don't really care. >> reporter: you don't care. >> no, i don't really care. they can just forget about me, i don't care. >> reporter: but they're not forgetting about you. >> that's their problem. they should, they should learn

how to forget about it. >> reporter: the chinese government wanted everyone to forget about ai wei wei, blocking his name on the internet in china and making it impossible to search for home. but that didn't stop ai wei wei from needling the authorities relentlessly. when they put his studio under surveillance, he decorated the cameras with lanterns. when officers were ordered to follow his every move, he got his own cameramen to film them filming him, ridiculing the state in a way no one else in china ever did. >> i mean, in a way, people learn to be, keep your head down, and ai wei wei doesn't, he's, no, i'm not going to keep my head down. i'm going to wave my big head with my beard and my crazy haircut all over the place, and you'll have to deal with it. >> reporter: he was making the chinese government look ridiculous. >> yeah, he was mocking it. he was mocking it.

and the chinese government is many things, but it does not possess an abundant sense of humor. and i think at a certain point, they said we're not going to take it anymore. >> reporter: and they didn't. early one morning in 2011 as he was about to board a plane, they put a hood over his head and took him away. it was the beginning of 81 harrowing days of solitary confinement. >> ai wei wei was eventually released but barred from leaving china for two years. you can see the full report on our website, cbs news.com. the overnight news will be right back. clearasil rapid action begins working fast for clearly visible results in as little as 12 hours. but can ot fix this teens skateboarding mishap? nope. so let's be clear: clearasil works fast on teen acne, not so much on other teen things.
