immigration, a key issue as the race for the white house moves into its final chapter. all of it coming just over a month after president biden ended his re-election campaign and endorsed harris as his replacement. peter alexander starts us off tonight here in chicago. >> reporter: you only get one chance to sell yourself to the people you want to work for and for kamala harris, tonight is the night. the first black woman and south asian-american to accept the nomination of a major party ticket. >> let us always remember when we fight we win! >> reporter: campaign sources tell nbc news tonight she'll focus on joy, optimism and patriotism, sharing her personal story, the daughter of a middle-class mom, detailing the contrast between her vision, a new way forward, she calls it and former president trump's and committing to be a president for all americans. the speech will cap off a stunning two months. harris who never won a primary or caucus vote instead was propelled to the nomination after president biden dropped out. >> joe, thank you for your

historic leadership. we are forever grateful to you. >> reporter: now enjoying a burst of democratic momentum, but also facing key challenges. she's a sitting vice president at a time when 80% of americans are dissatisfied with the direction of the country and polls show voters give mr. trump the edge on top issues like the economy and immigration. last night her new running mate tim walz, a former teacher and high school football coach, giving a pep talk. >> we've got the ball. we're driving down the field, and boy, do we have the right team. >> reporter: introducing himself and his family to america. >> hope, gus and gwen, you are my entire world. and i love you. >> his 17-year-old son gus in tears, shouting "that's my dad." later walz calling out mr. trump and his vp pick j.d. vance. >> leaders don't spend all day

insulting people and blaming others. leaders do the work. so i don't know about you, i'm ready to turn the page on these guys. so go ahead. say it with me. we're not going back! >> we're not going back! >> former president clinton accusing mr. trump of being obsessed with himself. >> the next time you hear him don't count the lies, count the is. >> oprah winfrey, electrifying democrats. her first-ever appearance at a convention. >> we are beyond ridiculous tweets and lies and foolery. these are complicated times, people, and they require adult conversations. >> urging americans, regardless of their party, to back the democratic nominee. >> we're all americans and together let's all choose kamala harris! >> reporter: peter, viewers at

home are likely to notice something out of the audience tonight, what is it? >> reporter: lester, it's going to be impossible to miss. many delegates are wearing white tonight in support of the women's suffrage movement, a nod to the history vice president harris could make if she wins becoming the nation's first woman president. lester? >> peter alexander, thank you. now to arizona and the manhunt for the suspect who also threatened to kill former president trump. this comes after the nominee campaigned at the border. garrett haake spoke to mr. trump. >> reporter: lester, the former president holding that campaign at the border in the midst of a man hunt. we have learned tonight that the suspect has now been arrested, all of this as i press the former president about his immigration plan and how he paid for them. tonight, former president trump holding an event in the shadow of the arizona border wall, as the sheriff announced there is a manhunt for a suspect wanted on unrelated warrants who also

threatened to kill a presidential candidate. multiple law enforcement sources tell nbc news it's trump. the former president saying he wasn't told about the threat. >> i have great respect for secret service. >> reporter: trump is in the midst of a battleground blitz with sources telling nbc news robert kennedy jr., is planning to endorse him tomorrow though talks are still ongoing. we've reporting that rfk jr. is getting ready to endorse you. what role would he have in your campaign or your administration. >> you're telling me something i don't know. i've always been friendly with him. if he were to endorse me i would consider that a great honor. >> despite what he's said about vaccine and 9/11 conspiracies, would that affect you if you're in the administration? >> it doesn't mean administration and certainly having his endorsement. things he agrees on, i agree on, there are many things that are perhaps the opposite of what you're saying, but he's a respected guy. >> we asked him about the democratic convention. >> what do you make about the attacks against you last night? >> well, that's all they have.

they failed on the border, as you can see. they failed on the economy and they failed on jobs. >> reporter: tonight trump going after vice president harris over border security. >> she wants to have an open border. >> we pressed him on his plan for mass deport oigdz. he offered no plan to pay for it. >> reporter: where will the money come from? >> it will cost trillions and in particular starting with the criminals. >> reporter: earlier we spoke to an undocumented immigrant from mexico who came 20 years ago and has two children who are american citizens. >> i don't think people can possibly understand what it feels like to live with the fear of deportation, she told us. >> reporter: if you deport millions of people and that would include mixed families. would you separate families to get to those goals? >> provisions will be made, but we have the criminals out. we have murderers in our country, they just walk in. we have over, in my opinion, over 20 million people came in and the number is growing every single day.

>> reporter: mr. trump returns to arizona tomorrow for another event. rfk jr. will be here, too, earlier in the day and it's increasing the speculation that the two could appear at a joint endorsement event and finally mr. trump will end the week in las vegas for one final stop in what is a multi-state counter blitz at the dnc. >> garrett haake, thank you very much. i am joined by "meet the press" moderator kristen welker and senior washington correspondent hallie jackson. kristen, we would always say this is a major night for the candidate, but you have the compressed timeline. >> absolutely. this is a big night. one of the things we'll be watching for. does vice president kamala harris explain how a harris administration would differ from the biden administration? so far she's released very few policy details and hasn't done an interview. we'll also be listening to her tone. democrats concerned that biden's strategy of trying to paint trump as a threat to the democracy hasn't resonated with voters, so we see more positivity.

how harris does tonight could determine whether the momentum she had coming into this week turns into a post-convention bounce. >> yeah, momentum, hallie, but at the same time this is still going to be a very tight race at the end of this week. >> it's incredibly competitive right now. it is incredibly close and there are those in the trump orbit who believe that ultimately this race over the next 70+ days will come down to issues like the economy and immigration. keep in mind the next time after tonight that we will see these candidates in these high-profile prime time moments will not be a party, it will be a face-off when the two take the stage for their debate. preparations have already started for both candidates. we understand the vice president has held one mock session and that will be a big moment and a big test for these two. >> hallie and kristen, thanks to you both. join us all evening on nbc news now for continuing coverage. speaking tonight governor gretchen whitmer, mark kelly and many, many more and join me on nbc starting at 9:00 p.m. eastern for the crescendo of the

convention as kamala harris accepting the democratic party's nomination. in arkansas, the state supreme court prevented an abortion rights initiative from appealing on the ballot in november. our senior correspondent laura jarrett joins us. what was the court's reasoning here? >> reporter: the high court said it came down to paperwork. advocate his managed to secure more than enough signatures. more than 100,000 signatures, in fact, but the high court said they hadn't met the technical requirements and so it will not appear on the ballot. that means arkansas will not join at least a dozen states that have tried to get these abortion amendments on the ballot including battleground states like arizona and florida. the upshot, of course, for women in the state which means the near-total ban which includes no exceptions for rape or incest will remain on the books there. it's all, of course, been a major topic at the dnc where you are in chicago, lester. >> all right, laura, thank you. three days after that super yacht sank off the coast of sicily in a violent storm, the

body of a british tech tycoon was recovered today. mike lynch was one of six passengers including two americans who were trapped on the yacht when it went down. his daughter is still unaccounted for. also tonight the major escalation as ukraine takes the fight to russia. ukrainian forces carrying out several strikes on targets inside russian territory including a port and a base. erin mclaughlin is in kharkiv. >> reporter: tonight, new video shows a critical ferry terminal which helps connect mainland russia to occupied crimea on fire. russian officials blame kyiv. so far, no comment from the ukrainians, and today the ukrainian air force released footage of another attack on russia, pointedly saying it shows a u.s.-made bomb being dropped on a russian platoon base in the kursk region. today ukrainian president volodymyr zelenskyy, the closest he's been to kursk since ukraine's surprise invasion.

he says he wants the region to become a buffer zone on russian soil to help protect major ukrainian cities to the east including kharkiv where today we saw first hand how in recent months the russians have been relentlessly bombing civilians including this shopping mall. nina says she was working back in may the day of the russian rocket attack. cctv footage shows her walking through the store and then -- >> translator: i fell on the floor. everything was falling on me, she says, and then i remember seeing the second rocket strike. >> reporter: miraculously, she survives. that same month across the city a recreational camp site also attacked. camp manager arthur berdov tried to save a pregnant woman, but he says she was already dead. he was later hit in his leg and hand. a ukrainian war crimes prosecutor tells nbc news that

ever since the kursk incursion there has been only one air strike on this city. tonight in kharkiv, at least, there's relief and fear the calm is temporary. lester? >> erin mclaughlin, thank you. in 60 seconds we'll have late developments on a dispute that halted freight trains in canada and threatened a supply chain right after this. the 11th-hour plan to avoid disaster. protect against rsv with arexvy. arexvy is a vaccine used to prevent lower respiratory disease from rsv in people 60 years and older. arexvy does not protect everyone and is not for those with severe allergic reactions to its ingredients. those with weakened immune systems may have a lower response to the vaccine. the most common side effects are injection site pain, fatigue, muscle pain, headache, and joint pain. arexvy is number one in rsv vaccine shots. rsv? make it arexvy. ♪ limu emu... ♪ and doug.
