that is about using ai first to expand the universe's possible materials and combinations of materials and then coupling that with autonomous experimentation to much more rapidly drive practical solutions that can be transitioned into production much more quickly. i love that because when i see an impossible problem, i am itching to find science and technology ways to make that turn into a trackable problem. if we can do that, there are just in manufacturing remaining and continuing to build in the u.s. which is part of the r&d effort. prof. miller: it has been a fascinating conversation. dr. prabhakar: great to be with you. [applause]

obama is among those speaking at a rally for kamala harris. live coverage on c-span. >> wow. what a crowd. i have one question for this crowd, are you ready to win? are you ready to elect kamala harris and tim walz? and are you ready to help me win

this united states senate seat? all right. now, isn't it great to have president barack obama with us tonight? i'm going to introduce him in a moment. i've got a couple things to say first. we are so grateful you are here tonight. you are here tonight because you love our country. that is why you are here tonight. and i cannot thank you enough for loving your country enough to be here with us tonight. this is a fight this year about a lot of key issues for families. but i think at the core of this campaign, at the national level, here in pennsylvania, it is a fight about two rings. the first is rights. the fight for voting rights, women's rights, workers rights. all on the line.

but this is also a fight about working families, about working together to help our working families to lower costs, to fight the fentanyl crisis, and to take care of the most vulnerable among us. our kids, seniors, people with disabilities, helping our veterans. that is what we do as democrats. now, i've got something to say about my opponent, a couple of things. my opponent is a former hedge fund ceo. and he told some lies in this campaign. he lied about living in pennsylvania when he was living in connecticut. he lied about how he grew up. he said he came from nothing. that is what he said.

he had a pretty good upbringing, like i did. we were lucky to have strong families and to grow up with a lot of advantages. he should tell a different story about that. he also lied about creating jobs in pennsylvania, when he outsourced jobs from pennsylvania to india and china. he should not lie about that. he also lied -- well, we just get past that. you know, this is a candidate who did not vote in pennsylvania for 15 years. while we are here in pennsylvania working for the people, working altogether like we all were, he was somewhere else in connecticut. you know what he was doing when he was in connecticut as a hedge fund ceo? investing in china, not pennsylvania. hear me out on this. he increased investments in

china by 108,000% when he was ceo. he invested in the company in china that made 90% of fentanyl. he invested in chinese oil companies and steel companies. he invested in companies making bombers and missiles to help china's military. when he did all of that, he was hurting our country and hurting the people of pennsylvania. that is what he was doing. boo is right. you know what he also bet against? when he was making investments, he bet against american steel companies, not bedding for american steel companies. -- betting for american steel companies. i want you to know, he has plans if you were to be successful. his plan is to give big tax breaks for you guessed it, the billionaires, the people making a lot of money, and the biggest corporations in the world. you know what happens when they

do that? they put medicare, medicaid, and social security on the chopping block. we are not way to do that in america. we are not going to cut those programs to give billionaires a tax cut. now, these out-of-state billionaires know that i won't vote for the tax cuts. i have already proven that. i voted against the billionaire tax cuts of 2017. so they are mad at me that i am going after them on corporate greed as well. you know what they are doing? we are spending more than $100 million to defeat me in this race. well i got news for those billionaires. i am going to beat david mccormick and i am going to beat those billionaires. [cheers and applause] yep. now, i need you to help me. i need you to help me. go to bobcasey.com and help us

to fight off those billionaires. we are grateful you are here tonight, because tonight we are here to focus on the future. the future of our commonwealth and our country. and tonight as well, we are honored tonight to welcome back to the city of pittsburgh, someone who has been here a lot, who campaigned here when he ran for president the first time, the second time, and helping candidates after that. you remember what he did. there's a lot we could list here, but i will just make it very brief. you know what he did to lead our country in passing the affordable care act, right? [applause] and i not only voted for that legislation, i fought off all the attempts to gut it and to repeal it. here's what that bill meant to the people of pennsylvania. there are 1.4 million

pennsylvanians who have health care solely because of the affordable care act. so, and we know that so many pennsylvanians, hundreds and hundreds of thousands of them, have coverage for pre-existing conditions because of that affordable care act. so tonight, tonight, as we come here tonight to talk about winning these campaigns for kamala harris and tim walz all the way down the ballot, we are also here to welcome back to pittsburgh and to thank him for his work for delivering for the people of pennsylvania when he was president, the 44th president of the united states, barack obama! [cheers and applause] ♪

[cheers and applause] fmr. pres. obama: hello, pittsburgh! are you fired up? are you ready to go? all right. it is good to be back in pennsylvania. it is good to be back in pittsburgh.

i love pittsburgh. you know, i love the people of pittsburgh. i love the food in pittsburgh. i don't usually do this, but this is a little bit of a yelp rating. i just had some of pamela's pancakes. i first had those, like, 10, 15 years ago when i was running. and i was like, i need some of those pancakes this time out. even though i am from chicago, some of you may know, when i was a kid i was a steelers fan. and watching the steelers this

season, i am not the only guy from chicago who likes being in pittsburgh. because so far, just fields is doing pretty good. now, before we get started, we have a moment of work to do here. so i want everyone to just settle in. we have some work to do. before we get started, i did want to say that we are heartbroken about the loss of life in florida, north carolina, states across the southwest. we are thinking about people's, families whose lives have been upended by the storms over the last couple of weeks. i could not be more grateful for the first responders and fema professionals who have put themselves in harm's way to try and help. [applause] you know, it's times like this

when we realize, having honest, competent leadership in government really matters. it makes a difference. and today i am asking you to vote for some of those leaders, including some folks we need working with your outstanding governor who you just heard from, governor josh shapiro. we need them in harrisburg. so we need them to vote for your next auditor general, malcolm kenyadda. your next attorney general, eugene depascale. your next state treasurer, eric mclean led. and my buddy, your outstanding united states senator, bob casey. [cheers and applause]

here in pennsylvania, there are three ways to vote. you can vote early, in person, at the county election office, or at a satellite office. you can also vote by mail. if you need to figure out how to do that, just go to iwillvote.com/pa to find a place to vote early or request a ballot. and of course you can vote at your election polling place november 5. but if you are at this rally, let's face it, you are probably voting, unless you are 12. so, you also have to help your friends and family make a plan to vote. even if you are 12, you can do that. talk to your mom and dad and aunts and uncles. because together, we have a chance to choose a new generation of leadership in this

country and start building a better and stronger and fairer and more hopeful america. now, you've already heard tonight, this election is going to be tight. because there are a lot of americans who are still struggling out there. still striving to make life better for themselves, for their families, and for their kids. and let's face it, as a country, we've been through a lot these last few years. we had a historic pandemic. wreaking havoc on communities and business. disruptions from the pandemic then caused prices to spike, and that put a strain on family budgets. and in many ways it has felt

like the aspirations of working people have taken a backseat to the priorities of the rich and the powerful. so i get it, why people are looking to shake things up. i mean, i am the hopey, changey guy. so i understand people feeling frustrated and feeling we can do better. what i cannot understand is why anybody would think that donald trump will shake things up in a way that is good for you, pennsylvania. i don't understand that. [cheers and applause] because there is absolutely no evidence that this man thinks about anybody but himself. i've said it before.

donald trump is a 78-year-old billionaire who has not stopped whining about his problems since he rolled down his golden escalator nine years ago. you've got the tweets in all caps, the ranting and the raving about crazy conspiracy theories. the two-hour speeches, word salad, just -- it's like fidel castro, just on and on. constant attempts to sell you stuff. who does that? selling you gold sneakers and a $100,000 watch, and most recently, a trump bible. he wants you to buy the word of god, donald trump edition. god is there right next to

matthew and luke. i mean, you could not make this stuff up. if you saw it on saturday night live you would say, no, that's going too far. no, he's doing that. it's crazy. and the reason he does it, is because all he cares about is his ego and his money and his status. he's not thinking about you. donald trump sees power as nothing more than a means to an end. he wants the middle class to pay the price for another huge tax cut that would mostly help him and his country club buddies. doesn't care if he costs more women their reproductive freedom because it will make a difference in his life.

do not boo. vote. [cheers and applause] they can't hear your boos, but they can hear your votes. most of all, donald trump wants us to think that this country is hopefully -- hopelessly divided between us and them. between the quote-unquote real americans who support him, in the outsiders who don't. because having people divided and angry, he figures boosts his chances of being elected. and he doesn't care who gets hurt. think about it. just the other day, we learned that on january 6, a couple years ago, donald trump was told that mike pence was in the

capitol about 40 feet from an angry mob chanting, "hang mike pence." and his response was, quote, "so what?" don't boo. if donald trump does not care that a mob might attack his own vice president, do you think he cares about you? pennsylvania, we do not need four more years of that. we don't need four more years of arrogance and bumbling and bluster and division. america is ready to turn the page. we are ready for a better story, one that helps us work together instead of turning against each other. pennsylvania, we are ready for a president kamala harris.

[cheers and applause] and the good news is, kamala harris is ready to do the job. this is a leader who has spent her life fighting on behalf of people who need a voice and a chance. somebody who was raised in the middle class. who worked a summer job at mcdonald's while she earned a degree. who believes in the values that built this country. somebody who has served with distinction in every office that she has ever held. i think we probably had a fainting spell back there, so let's make space for the emergency folks. this happens sometimes. everybody bend your knees a

little bit. you have been standing for a while. you can dance if you want. she'll be ok. kamala is as prepared for the job as any nominee for president has ever been. that's who kamala is. and in the white house, she will have an outstanding partner in governor tim walz. tim is a veteran, he is a teacher, he's a coach, he's a hunter, he's been a great governor working with democrats and republicans to get stuff done. he can also take a vintage truck apart and put it back together again. you think donald trump can do that?

for that matter, do you think donald trump has ever changed a tire in his life? i'm just trying to picture it. [chuckling] the point is, if you elect kamala and tim, they won't be focused on their problems, they will be focused on yours. they understand that too many folks here in pennsylvania and across the country are struggling to pay the bills. even though wages are steadily growing and inflation is finally slowing, the price of everything, from health-care care to housing and groceries, it is still too high. that takes a real bite out of paychecks. it hurts. so the question is, who is

really going to do something about it? that is what you should be asking yourself. now, donald trump's plan is to do what he did last time, which was given another massive tax cut to billionaires and corporations. don't boo. i'm going to break you of this habit. and the reason some people think , i remember that economy when he came and was pretty good. yeah, it was pretty good. because it was my economy! [cheers and applause] we had had 75 straight months of job growth that i handed over to him. it wasn't something he did. i spent eight years cleaning up the mess that the republicans had left me the last time. so just in case everybody has a

hazy memory, he didn't do nothing. except those big tax cuts. now, his other big economic plan now is to slap tariffs on everything, from food to tv's. now, understand what tariffs are. anything that is made elsewhere and comes here, you slap extra money on top of it. and if other countries are cheating, in some cases it makes sense because you want to have a fair playing field. but what he is proposing is basically a trump sales tax that could cost the average family almost $4000 a year. so, if you are concerned about higher prices, that is not the way to get lower prices.

that's going to come out of your pockets. you think prices are high now? donald trump's message basically is, you ain't seen nothin' yet. all right, so as far as you can tell, that's his plan, because it's not written down anywhere. when it comes to health care, you heard it in the debate. donald trump has got one answer. ending the affordable care act that 45 million people rely on. the other day his running mate, j.d. vance, had -- [booing] [laughter] you gotta vote. the other day his running mate had the nerve to say donald trump salvaged the affordable care act.

[laughter] i mean, donald trump spent his entire presidency trying to tear it down. and by the way, he couldn't even do that right. and now, eight years after he was elected, when he was asked about what he was gonna do, he says he's got concepts of a plan for how he'd replace it. now, i want y'all to think about this for a second. let's say your boss gives you an assignment, a project. he says, i need this on friday. friday comes around and he says, so, did you finish that project i asked for? you say, well, i actually haven't started, but i have a concept of a plan. or you could try it at home.

uh, honey, did you do the dishes? i have a concept of a plan to do the dishes. how's that gonna go over? if it wouldn't work for you, why in the heck should work for the president of the united states? but the good news is, kamala harris, she doesn't have concepts for a plan. she has an actual plan to make your life better. [cheers and applause] to bring down the cost of things like groceries, she will go after corporations that are jacking up prices. just like she went after big banks and for-profit colleges when she was attorney general in california. and believe me, when she does, nobody is going to want to stand in her way.

i remember after the whole mortgage crisis, kamala pushed me and my administration harder than any other attorney general in the country to make sure homeowners got a fair settlement. it did not matter that she was pushing a democratic administration. she was not going to let anybody stop her from winning as much relief as possible for the families who deserved it. and because of the work that she did, those families got billions more than they would have otherwise got. that is the kind of president kamala harris will be. to lower housing costs, kamala will cut red tape and work with governors like josh shapiro, as well as the private sector, to build three million new homes.
