conflicts of interest, involving his businesses. we get details from nbc's hallie jackson. >> she should be locked up. >> reporter: some promises he ran on as candidate, now looking less likely as president-elect. starting with his pledge to prosecute hillary clinton for her e-mail server. >> she has to go to jail. donald trump confirms what a source close to him first told nbc. quote, it's just not something that i feel very strongly about. >> well, so much for locking her up, i guess. >> reporter: trump, who doesn't have the power as president to prosecute anyone, tells "the new york times," i don't want to hurt the clintons, adding, she went through a lot and suffered greatly in many different ways. breitbart, the conservative outlet that's backed trump is blaring the headline, broken promise, with the news now of maybe another one.

paris accord. signed by nearly every nation in the world. >> we will cancel this deal so that our companies can compete. >> reporter: today he says he has an open mind about the deal. the walkback raising questions about what he will do as president and what he's already done in his businesses and charity. the trump foundation reporting in a new filing, it violated irs rules. tax experts say correcting that could require paying taxes and possible penalties. on the business side, unanswered questions about how he'd wall off his personal interests of the country. suggesting on the trail, it wouldn't be an issue. >> i wouldn't even be thinking about the business. i mean, who cares. i would actually say, who cares? >> reporter: now trump's brushing aside fears of conflicts of interest, pointing out, the law is totally on my side. he's right. the president is exempt from conflict of interest laws. but not from constitutional provisions forbidding foreign gifts. the president-elect today also condemned

washington of members of the alt-right. a conservative extremist movement with ties to white nationalism. he added, he doesn't want to do anything to energize that group. lester? >> hallie jackson, thanks. now to the travel headaches that could be ahead for millions getting set to head to the airport for thanksgiving. winter storms from the rockies to the plains and up into parts of the northeast. we have it all covered starting with nbc's blake mccoy. >> reporter: for the residents digging out from yesterday's massive snowfall. upstate new york, seeing as much as 40 inches of snow in just the past two days. >> can't get out the side door yet. we got out the back door. [ laughter ] >> reporter: northern pennsylvania, digging out from 15 inches and even bigger snow drifts.snowdrifts. >> you don't want to hit those drifts. you'll be buried in

getting socked again. colorado too. all leading to a challenging start for holiday travel. nearly 49 million people on the move this thanksgiving, up a million over last year. the biggest travel rush since 2009. you can thank low gas prices and cheaper airfares. chicago o'hare is debuting new automated screening lanes designed to get people through 30% faster. if you do run into problems flying this year, social media could be your friend. >> some of the airlines are answering twitter a lot faster than they would a phone call. >> reporter: now if only a tweet could dig you out of this. blake nbc news meteorologist dylan dryer is here with us. we're about to get hit with one of the busiest travel periods. where should people be on the lookout for the bad stuff? >> the pacific northwest and the midwest, that's where the next two storms are moving through. if we start on wednesday, for those of you traveling by air, we could see most of our delays across the midwest. mostly in the chicago area, because of poor visibility and also the possibility of seeing some heavier pockets of rain.

occasional showers during the day in seattle, but then heavier rain starts to move in overnight. if you're traveling by road, especially through the tennessee and ohio river valleys from chicago to nashville, we could see rain and storms early on. then improving conditions later in the day. the mountain passes in the pacific northwest, because of the snow, will cause significant slowdowns as well. as we go into thanksgiving itself, most of the coy but we're still looking at possible delays across the pacific northwest due to rain and mountain snow. in the pittsburgh area, that's where we could see most of our scattered showers and some rain will last through most of the morning with improvements during the day. we are looking at a wintry mix of rain and snow in the buffalo area early on, changing to rain later in the day. on sunday, as people return home, it doesn't look like many trouble spots at all. >> dylan dryer,

today with a new record. the dow industrials were up 67 points today, to close above 19,000 for the first time in the dow's history. the nasdaq and s&p closed higher as well. the issue of jobs and bringing back those jobs lost overseas is at the center of donald trump's plan to pull out of the transpacific partnership. that's the big trade to last year. but last night, mr. trump said he would get rid of it on day one of his presidency. we get more on this tonight from nbc's jacob rascon. >> reporter: ulysses trotter was always going to be a factory worker. >> my livelihood, the way that i can raise my family, take care of my family, same way that my father did. >> reporter: in february, the chattanooga factory that provided for their families for decades, plans to downsize. those jobs, he says, shift overseas. >> cannot compete with them. we could probably do that, do those jobs now for free and we still couldn't compete

would only intensify with the transpacific partnership or tpp, which the president-elect says will go. >> i'm going to issue a notification of intent to withdraw from the transpacific partnership, a potential disaster for our country. >> reporter: it's a free trade agreement between the united states and 11 other countries, including japan, mexico, and vietnam, that would lower trade barriers and taxes for u.s. goods. the winners in global trade deals often consumers who pay lower prices. the losers, often american workers, forced to compete with lower cost competition overseas. to save all our jobs and have markets in the world open to american goods. we've got to have some trade-off, and that trade-off tends to be low value manufacturing jobs. >> reporter: in baltimore, drew greenblatt said tpp would help him add jobs. >> we need new markets to sell to. we need new clients to grow into. >> reporter: but it's an argument that doesn't convince trotter, it's why he supports trump's view on trade.

of his top priorities, that's good for you? >> it's good. people got to hold him to do it. he can't just be saying it and not do it, also. >> reporter: one family fearing a way of life is at stake. jacob rascon, nbc news, chattanooga, tennessee. a hollywood star spoke out for the first time on television today about a personal battle with prostate cancer. ben stiller rose to fame in some of the biggest blockbuster comedies of the last couplead serious, hoping to save lives by sending a message, every man should talk to their doctor about getting tested. we get his story from nbc's miguel almaguer. >> reporter: a man of many roles, today ben stiller celebrates one of his most important -- real-life cancer survivor. >> anybody who's had cancer, you know you have to keep on checking on it. but i'm really fortunate. >> reporter: speaking to matt lauer on "today" with his surgeon, stiller wants to send a message to men about getting

>> if it was up to me, i'd say every guy should go and get tested after the age of 40, 45. especially if you have a family history. >> reporter: the test itself, known as the psa, is easy. simple blood work. but some experts caution against routine testing, saying the psa can be unreliable and lead to overtreatment with painful side effects. >> this is a discussion the doctor has to have with their patient. the treatments for prostate cancer all have risks around urinary function and sexual function and other risks. so you want to treat american cancer society recommends all men talk to their doctor about the benefits and risks of having the test, starting at age 50 for those with an average risk, and age 45 for high-risk patients like african-americans and those with a family history. but according to those guidelines, stiller, age 46, with no family history when diagnosed, should not have gotten the test. >> if i hadn't taken this test, i wouldn't

it had probably become something that was not going to have the outcome, in terms of the treatment that it did have. >> reporter: tonight the beloved comedian, grateful for a life-saving test that he is deadly serious about. miguel almaguer, nbc news, los angeles. and some troubling news tonight, having to do with the zika virus. the doctor who first sounded the alarm now says infected babies who were born appearing healthy could have defects after all. the cdc studied 13 such normal looking infants, and 11 of them now have microcephaly, a medical term for a smaller head which can cause brain damage. there's a lot more to tell you about. school bus dangers, how the bad driving is not limited to a few isolated incidents. the alarming findings of an nbc news investigation. also, the ordinary bucket that started a nationwide movement, now headed for its place in american

we're back now with a deeper look at school bus safety and bad driving after the deadly crash in tennessee. an investigation by our dallas station, kxas, found widespread problems with drivers in that city and well beyond. scott freedman has more on the disturbing

past red lights, risking dangerous collisions. one bus driver nearly rear ending a car before running the red light. >> they are responsible for the safety of our children. they know better. >> reporter: in dallas, the area's largest school bus agency fired 13 drivers, and suspended 229 more after an nbc news investigation uncovered these red light camera videos, along with nearly 500 tickets over a two and a half year span. 1,700 complaints, called in by witnesses alleging reckless driving. >> we are taking the steps necessary, both systemic and personnel, so that this will not and cannot happen again. >> reporter: but from illinois to florida, to arizona, red light cameras show it happens in other cities, too. in new york, drivers at several bus companies accumulated more than 6,000 speeding and red light violations in just two years. in miami, and nearby

traffic tickets while driving school buses but continued to drive, one even on a suspended license. safety experts say it's ultimately up to bus company managers to police bad driving. >> if there's dangerous driving behavior, if there are bad habits that are out there, they need to be addressed and it needs to be done quickly. >> reporter: but that was not happening in dallas. nbc news discovered the agency that runs the buses never disciplined a single driver caught in those red light camera taxpayer money to pay the tickets and the drivers walk away with no punishment, until we flagged it. statistically school buses are still the safest way for kids to get to school, but the chattanooga crash and these images are a wake-up call for swift punishment if drivers are reckless. scott freedman, nbc news, dallas. and we're back in a moment with a milestone for one of the most famous baby
