course it still is, but i will tell y'all this, if i lived in pennsylvania, i would have already cast my vote for john fetterman for many reasons. >> reporter: oprah saying her vote is about the values we hold dear, the values of inclusion, the values of compassion. in his closing pitch to voters, fetterman, who is recovering from a stroke, says that experience has given him new fight. >> i think if somebody was looking for the kind of candidate that is to stand up for anyone that ever got knocked down that has to get back up, or any kind of forgotten community, and that's really what our -- this campaign is absolutely about. >> reporter: today the oz campaign responding to oprah's endorsement, saying, dr. oz loves oprah and respects the fact that they have different politics. the candidate is spending the campaign homestretch reaching out to a key group of voters, suburban women, urging supporters to share his finely tuned message with their neighbors. >> so, your job is to highlight -- what are the three things? the economy, crime, and the border. right? three things.

about john fetterman and dr. oz. >> there has been movement in pennsylvania, but it has been slight, and it is not enough to break this dead heat we are seeing between fetterman and dr. oz. both at 46%. too early to tell if that endorsement from oprah will make any of the difference. but, again, you said it, this is a state where you'll see two former presidents campaigning. over to georgia, it is dead even here between senator rafael warnock and the republican herschel walker. and right to nevada, we are seeing much of the same. another close race between democratic incumbent catherine cortez masto and the republican, adam laxalt. david, with races this tight, it's all going to come down to voter turnout, the ground game. but this is shaping up to be one of the most unpredictable midterms yet. >> no question. along with linsey davis, jon karl, political director rick klein all right here on the desk here on election night. here and across the country live in the battlegrounds. our live coverage all evening long begins at 8:00 p.m. eastern election night. again, next tuesday night.

jaw-dropping number, the $44 billion musk paid for the company, billions more than most analysts believe it's worth, and the nearly $13 billion he borrowed to close the deal. to try to raise revenue, musk floating the idea of a pay-to-play platform, an $8 monthly charge for verified accounts with the blue checkmark. but the platform profits most from ads, and companies are increasingly concerned about musk's plans to change how twitter moderates content. one study shows an unsettling increase in hate speech on twitter since musk took over. at an investor conference in new york city today, musk blamed pressure from activists who fear the platform becoming a playground for hate speech. >> we've done our absolute best to appease them, and nothing is working. so this is a major concern, and i think this is, frankly, an attack on the first amendment. >> reporter: and, david, critics like the naacp say this is not a first amendment issue, calling

on companies to pull their ads from the platform until twitter, quote, rids itself of any content or account that spews hate or disinformation. that, of course, creates a big challenge as musk tries to make twitter profitable. david? >> all right. janai norman tonight here in new york. janai, thank you. tonight after we reported around synagogues, the fbi reporting they have found the individual whose threat prompted that issued rare warning to synagogues in new jersey. police scrambled to add patrols outside synagogues. sources telling abc news that a young adult was interviewed about concerning social media posts. he reportedly told them he dislikes jewish people, but had no plans to do any harm. it is unclear tonight if that person will be charged. meanwhile, nba star kyrie irving has apologized after posting a link to an anti-semitic movie. the brooklyn nets taking action after he refused to apologize immediately and make clear that he had no anti-semitic beliefs. the nets saying he is, quote, currently unfit to be with the team.

missile aimed toward japan. >> this is an unprecedented level of activity. the intent here is to ramp up tensions as a prelude to a likely underground nuclear test sometime in the days to come. >> reporter: that test is expected any day, the first in five years. but the u.s. warning that if kim ever attacks with a nuclear weapon, that would be the end of his regime. the joint u.s./south korean military exercises end this weekend, but u.s. officials don't think that will have any effect on kim's desire to test a nuclear device. david? >> all right. martha raddatz tonight. martha, we'll see you here on election night as well. thank you. in the meantime tonight, the warning to vladimir putin over nuclear weapons. china's president xi making his most direct criticism of putin's war in ukraine yet, now warning against resorting to nuclear weapons. it came during a visit with the german chancellor in beijing. the u.s. and its allies, including germany, had been urging xi to take a stand. tonight, the pentagon announcing new military aid to ukraine.
