attorney general jeff sessions warned that cities that don't help enforce immigration laws may lose federal grant money. ben tracy has more about the trump administration's efforts and who's being targeted. >> he stepped out, and he never came back in. >> reporter: 19-year-old estephanie ortiz says agents came to her house in pasadena last month looking for someone who did not live there. they arrested her father, carlos ortiz instead. he was in the country illegally but had no criminal record. >> why did we open the door? nobody's going to want to open the door. everybody's scared. >> reporter: the los angeles police department says aggressive ice enforcement tactics are also having a chilling effect on latinos report being crimes. since the beginning of the year, reports of sexual assault by

latinos dropped 25%. domestic violence reports fell 10%. >> they start to clam up. they no longer come to court. >> reporter: california supreme court justice says latinos tell her they are now afraid to show up at courthouses. so she wrote a letter to attorney general jeff sessions, accusing agents of stalking undocumented immigrants to make arrests. in our courthouses. >> i feel like they are being targeted in a way that's unprecedented. >> reporter: what is your concern if ice agents are in courthouses? >> victims aren't going to come to court. witnesses aren't going to come to testify against bad guys in violent communities, because they're afraid they're going to get arrested in court. >> reporter: in a statement, ice said, while ice does arrest targets at courthouses, generally, it's only after investigating officers have exhausted other options. but in response to ice actions, a proposed bill in california

would bar state and local police from aiding federal immigration enforcement, including turning over criminals when they're released from jail. l.a. county sheriff mcdonnell says that's a bad idea. >> by not allowing them access to the jails, the likelihood is they're going to go into the communities looking for the individual, and they're not going to limit themselves to that individual. >> reporter: and to give you an idea just how much federal money is now at stake, san francisco and new york could lose nearly $25 billion combined, scott, if the trump white house follows through and cuts off funding for sanctuary cities. >> ben tracy, thank you. the president's failure to repeal and replace the affordable care act at least on his first try has been a disappointment to many who support mr. trump but has been a relief to those who depend on obamacare. don dahler has been looking into that. >> reporter: her 2-year-old son has been in the hospital a lot these days.

he's covered under the aca, but wynter voted for trump. >> i'm a republican. so i stay true to my party and our principles. >> reporter: and although she sees problems with the aca, she's grateful for some of the benefits. >> well, the main thing for the aca for me is of course the preexisting conditions, that is huge. i mean, he has two major life-altering conditions that if i had to go and shop for it, it, i wouldn't be able to afford it. >> reporter: wynter lives in quakertown, pennsylvania, whose congressman, brian fitzpatrick was one of dozens of republicans who planned to vote no on the new health care bill before it got pulled. he opposed the bill because it didn't do enough to address opioid addiction treatment. pennsylvania has over 700,000 enrolled in medicaid expansion and more than 426,000 in the aca marketplace. had the aca been repealed, the pennsylvania budget and policy center estimated over 1 million

pennsylvanians would lose their coverage, like brian kline who was diagnosed with cancer last year. >> the aca saved my life and saved me from medical bankruptcy. >> reporter: kline is a democrat who voted for clinton, but he and wynter have one thing in common. their message to congress on health care. >> stop fighting, stop arguing, stop holding your arms and saying, i'm a republican, i'm a democrat, come together. that's why we elected you. >> reporter: both wynter and kline say they want the democrats to cooperate with the president in order to make the problems with obamacare better. >> don dahler, thanks. today the white house condemned the mass arrests in moscow during rallies against vladimir putin's government. the protests were organized by one of putin's fiercest political opponents, and elizabeth palmer is following this. >> reporter: united in anger. russians from across the country marched to protest against official corruption.

in moscow, it was the biggest demonstration since the anti-kremlin rallies of 2012. but, without a permit, authorities called the gathering illegal and soon the police had moved in. hundreds were arrested. including alexei navalny, an opposition leader and ferocious critic of president putin and his famously corrupt administration. earlier this month, navalny released a video alleging that the prime minister had amassed a fortune in mansions, yachts and vineyards, all through corrupt deals. the video went viral. and here's the reaction. the protesters message to the government? shame on you. navalny's now an opposition icon. after his arrest, supporters

surrounded the police van, shouting "don't let them through"! and police were forced to lift cars left as obstacles out of the way. navalny appeared in court today and was handed a fine and a short jail sentence. scott, these arrests have raised eyebrows in washington. they're seen as more heavy-handed stifling to any opposition to president putin. but alexander navalny's not going anywhere. in fact, he says he's going to run against mr. putin next year for the presidency. >> liz palmer, thank you.

but many analysts and researchers say it will be much higher, between $15 billion and $40 billion. here's what the president wants, aside from being 30 feet, the wall has to prevent digging or tunneling below it for a minimum of six feet. a person must not be able to climb to the top of the wall or access the top of the wall from either side unassisted. the wall has got to be so tough that it would take someone an hour to break through it if they're using a sledge hammer, pick ax or chisel. and on top of that, it must be aesthetically pleasing. mr. trump wants a beautiful wall. now one of mr. trump's most recent tweets trumpeted the figure of border crossings being down. that's a fact, it's true. but border patrol says the number is down because it usually is this time of year. they expect it to go back up as the weather gets warmer. >> david begnaud for us at the southern border. thank you. up next, doctors tell us what they would do to fight the opioid epidemic.

>> if you call it a disease, now you've got to help me out. you know, you've got to not just throw me away. >> reporter: for davis, it includes counseling and medication. dr. ward is his physician. she supports the new recommendations, including a comprehensive approach to care. >> the old traditional model of sending patient to detox and hope that they will get better is really, we know that it doesn't work. there's no evidence. >> reporter: and we were struck by this. more than 70% of people with hypertension, diabetes or major depression get treatment, scott, for substance abuse it's less than 20%. >> and yet treatment works. dr. jon lapook. thank you, doctor. in new york city, the fearless girl will stand her ground a little while longer. the statue staring down wall street's charging bull has become a huge hit with tourists. it was placed there temporarily to highlight gender disparity in the boardroom. but today the mayor said she can stay until february. in a moment, a young girl who's inspiring the world with her singing.

this is the "cbs overnight news." welcome to the overnight news. i'm jericka duncan. the republican chairman of the house intelligence committee, devin nunes is used to asking tough questions, but now he's the one on the hot seat over the way he's been handling classified information about russian ties to the white house. jeff pegues reports. >> reporter: devin nunes, the chairman of the house intelligence committee says he was at the white house grounds last tuesday, to meet a source and look at highly classified information in a secure location. >> i've been working this for a long time with many different sources and needed a place that i could actually finally go, because i knew what i was looking for, and i could actually get access to what i needed to see. >> reporter: tuesday's visit to

the white house complex was the start of several days of unusual meetings and conflicting disclosures. on wednesday, nunes revealed to the press that he had seen evidence that the obama administration had intercepted communications involving members of the trump transition team. nunes then returned to the white house to personally brief the president before disclosing the information to members of his own committee. on thursday, he was forced to apologize for keeping them in the dark. by friday, nunes seemed less certain of his claims. >> it's hard to know where the information came from until you get the reports and have time to go through them and see all the sourcing of the documents. >> reporter: nunes has denied that his source is from the white house. today white house spokesman sean spicer said even he doesn't know where the information came from. >> i can't say 100% that i know anything he briefed him on. >> it's possible. >> anything's possible. >> reporter: democrats say nunes's behavior makes it

impossible for him to continue investigation into russian involvement with trump associates. senator chuck schumer. >> chairman nunes is falling down on the job and seems to be more interested in protecting the president than in seeking the truth. >> reporter: it is unclear why nunes chose to view the classified information at a secure location on white house grounds. there are similar facilities in other government buildings. nunes says that he needed access to a specific computer network that was not available on capitol hill. the latest trump administration official to be hauled before congress is the president's son-in-law, jared kushner. he's agreed to be interviewed by the senate intelligence committee. major garrett has that story. >> reporter: the previously undisclosed meeting took place during the trump transition, before jared kushner stepped down as head of his real estate firm.

in december, kushner sat down with russian ambassador to the u.s., sergei kislyak at trump tower, a meeting the trump team had previously confirmed. but afterward, kislyak asked kushner to meet the head of a and russian intelligence the bank is run by sergey gorkov who once trained at the spy in2016, another official, buryakov,dh sentenced to recruit u.s. spies for 2014 annexation of crimea. russia. i told you. >> reporter: the president has
