to her private e-mail. her team is hoping this means she'll be cleared of wrongdoing before she accepts the democratic nomination for president just weeks from now. charging ahead with vetting potential vice presidents, hopefuls spanning out to defend her sunday. >> i think that there won't be an indictment and i think that means that she did what many secretaries of state have done in the past. >> reporter: clinton taking in a saturday evening performance of "hamilton" on broadway after she and top aide cheryl mills spent the morning the fbi headquarters. officials from the justice department and the fbi interviewing her for more than three hours about her use of private e-mail as secretary of state. clinton telling nbc's chuck todd she wanted to get it over with. >> i've been eager to do it and i was pleased to have the opportunity to assist the department in bringing its review to a conclusion. >> reporter: meanwhile, donald trump dealing with his own problems. his team still not explaining the image posted to his twitter account on saturday, attacking

clinton as corrupt, showing what appeared to be a star of david over a pile of money, an image that also appeared two weeks earlier on twitter, posted by a user who promoted other racist imagery. on trump's feed, the image was quickly replaced with a modified version. but with 2 of the 6 points of the star still visible. his former campaign manager defended him. >> i tweet >> a tweet in the bottom line -- >> reporter: but the anti-defamation league took him to task saying, "it is long overdue tore mr. trump to reject the anti-semit itits and racisth the same clarity and energy he's brought to the campaign trail when calling out other candidates. trump's campaign didn't respond to repeated requests for more explanation of that tweet. and in the past, trump has praised his son-in-law's jewish faith. trump and clinton are both planning to be back out on the campaign trail after the fourth of july holiday.

they're on a collision course in north carolina. clinton's going to appear for the first time when president obama in charlotte, and then donald trump is rallying in raleigh just hours later. >> that's going to be an interesting day. kasie hunt, thanks. donald trump has a penchant for using nicknames to try and bilittle his adversaries. for weeks he's been mocking hillary clinton ally senator elizabeth warren accusing her of exaggerating her native american katy tur has been looking into trump's record. >> she said she's native american. i said pocahontas. pocahontas. >> reporter: donald trump attacking elizabeth warren's claim of native ancestry. it is not the first time trump has infuriated native americans. in the early '90s trump tried to block the spread of gaming, competition for his atlantic city casinos. he filed a lawsuit in federal court and testified before congress claiming indian casinos

association. hill says trump hasn't changed. >> the same style and the mccarthyism tactic, fear mongering, the same thing he did back in '93. he is not out of character, he's just including more people of color. >> reporter: trump quietly dropped his lawsuit in 1994 and tried to join forces with native americans. making overtures to tribes in washington state and florida to develop casinos. but neither effort took off. the trump campaign didn't respond directly to the content of this story instead saying that this is nothing more than nbc news trying to bail out hillary clinton's terrible very bad weekend by unfairly attacking mr. trump. it goes on to say that the real story this weekend was clinton's meeting with the fbi. >> which we covered. katy tur, thank you. in california tonight, they're battling fires in several parts of the state, including a big wildfire in central california that threatens dozens of homes.

as millions of americans hit the road this holiday weekend, more than a few might get stopped for speeding. but in south carolina, some drivers are fighting back, filing a class action lawsuit against a town they claim is running an illegal speed trap. as gabe gutierrez reports, millions of dollars could be at stake. >> reporter: it was a road trip dusty holman would rather forget. >> i definitely feel ripped off. >> reporter: on his way to myrtle beach, the navy veteran was driving through the tiny town of turbeville, south

carolina, population 800, when he was pulled over. >> i was speeding and i was definitely willing to pay the ticket. >> reporter: but this one was different -- $388, citing a town ordinance passed in 2003, much higher than the typical state fine but with an up side -- no points assessed on his license. >> speed trap is basically what that is. >> reporter: he ended up fighting the ticket, ultimately paying $150 for the state penalty but getting points on his record. this retired couple was also stopped driving back from a vacation in florida. >> of course, it is not fair. this is how they support the town, then there's something wrong. >> reporter: now a class action lawsuit has been filed alleging the town covering less than two square miles is being unjustly enriched by using a local ordinance to fine drivers when a state law is already on the books. despite repeated requests for an interview, town officials here declined to speak to us on camera citing the ongoing lawsuit. police chief previously told nbc station wois that it the

ordinance made the streets safer. attorney representing the town now says it plans to challenge the legal basis of the claim, specific lip the abili specifically the ability of an individual who has voluntarily pled guilty to forfeit a presumptive valid town ordinance. in 2013 wois watched as the chief wrote multiple tickets on labor day stopping several out-of-state drivers. >> it's morally wrong and i don't think we should tolerate it. >> reporter: state representative jimmy bales has unsuccessful tried to pass legislation to block the local ordinance. >> it is illegal, absolutely. highway robbery. >> reporter: what began as costly road trips now turning into a legal battle far beyond traffic court. gabe gutierrez, nbc news, turbeville,

be about learning lessons. >> you got to be mentally strong. sometimes i break down. sometimes i don't. but i can't. i'm in this predicament, i got to get it over with. >> reporter: at new york's infamous rikers island jail, some of those lessons by necessity are quite literal. >> new york state is 1 of 2 states that considers 16-year-old adults. and 1 of 10 states that considers 17-year-old adults. >> reporter: so you're obligated to teach those kids. >> well, we're obligated to provide age-appropriate programming. >> reporter: island academy is an alternative high school on rikers educating youth on the inside. but it is the lessons they learn once they're back on the outside that can determine their futures. >> we offer a combination of things. we know that in order to thrive, young people need a sense of belonging a inin ining and they opportunities to achieve. >> for this situation, who's creating this problem? >> reporter: and that means a net to catch them, which is where friends of island academy comes in. getting to young offenders

responsibility as fathers and being in a child's life just makes me every day when i wake up to not be a statistic. >> reporter: like the one that says half of young adults released will likely go back to jail unless someone is there to show them another path. >> i'm just going to go home a better person. go home a better person and don't come back. >> our thanks to my friend, lester holt, for that report. when we come back, we'll take you inside the training program for dogs doing their part to keep our airports safe. thanks for the ride around norfolk! and i just wanted to say, geico is proud to have served the military for over 75 years! roger that. captain's waiting to give you a tour of the wisconsin now. could've parked a little bit closer... it's gonna be dark by the time i get there. geico®. proudly serving the military for over 75 years.
