With less than a week to go until the 2024 election, more than 57.5 million Americans have already voted, according to the Election Lab at the University of Florida. The number represents more than a third of the total turnout for the 2020 elections – it is hard to say what it means, as 2020 saw a high number of mail-in votes because of the Covid pandemic, but turnout in some states indicates that the Republican push for supporters to vote early is working.

Dressed in an orange hi-vis vest after a campaign stunt in a garbage truck, Republican nominee Donald Trump used a rally in Green Bay, Wisconsin, to take aim at the Democrats over Joe Biden’s “garbage” comments, thanked sanitation workers and promised to protect women “whether they like it or not”.

Elsewhere in Wisconsin, Kamala Harris appealed to first-time voters, for whom she said the issues of climate change, gun control, and abortion access are “not political. This is your lived experience.” She was speaking shortly after a new CNN poll showed her six points ahead of Trump in the state.

Here’s what else happened on Wednesday:

Kamala Harris election news and updates

• Harris spoke in Harrisburg, the Pennsylvania state capital, which is in one of the few counties that voted for Joe Biden in 2020. Polls show a tied race in Pennsylvania, which both campaigns are competing fiercely for. The path to winning 270 electoral votes is much more difficult for the candidate who loses Pennsylvania. Harris did not mention the racist remark about Puerto Rico made by a comedian at Trump’s Madison Square Garden rally on Sunday, but the state’s sizeable Latino and Puerto Rican population could be a decisive voting bloc.

• The former Republican governor of California Arnold Schwarzenegger has announced that he is backing Harris in next week’s election. In a long post on X, Schwarzenegger, 77, said that while he doesn’t “really do endorsements”, he felt compelled to formally endorse Harris and her pick for vice-president, Tim Walz.

• In an op-ed for the Guardian, Vermont Senator Bernie Sanders addressed progressives’ concerns about voting for Harris given the Biden administration’s stance on Israel’s war on Gaza. “I understand that there are millions of Americans who disagree with Joe Biden and Kamala Harris on the terrible war in Gaza. I am one of them,” he writes, adding that “on this issue, Donald Trump and his rightwing friends are worse.”

Donald Trump election news and updates

• Before his Green Bay rally, refused to apologise for the comments made about Puerto Rico at his Madison Square Garden rally, instead repeating his assertion that he did not know who the comedian was or how he got booked. “He’s a comedian, what can I tell you? I know nothing about him. I don’t know why he’s there.”

• A Pennsylvania judge on Wednesday sided with Trump’s campaign and agreed to extend an in-person voting option in suburban Philadelphia, where long lines on the final day led to complaints voters were being disfranchised by an unprepared election office.

• The House speaker, Mike Johnson, said there would be “massive” healthcare changes if Trump wins next Tuesday, including abolishing Obamacare. “Healthcare reform’s going to be a big part of the agenda,” Johnson, speaking at a rally in Pennsylvania on Monday, told the crowd. “When I say we’re going to have a very aggressive first 100 days agenda, we got a lot of things still on the table.”

Elsewhere on the campaign trail

• A Republican former congressional candidate was charged with stealing ballots during a test of a voting system in Madison county, Indiana, state police said on Tuesday. During the test on 3 October, which involved four voting machines and 136 candidate ballots marked for testing, officials discovered that two ballots were missing, according to the Indiana state police.

• A majority of voters in swing states do not believe Trump will accept defeat if he loses next week’s presidential election and fear that his supporters will turn to violence in an attempt to install him in power, a new poll suggests.

• The pace of US economic growth slowed over the summer but continued its two-year expansion, according to data released on Wednesday. US gross domestic product (GDP) – a broad measure of economic health – rose by 2.8% in the third quarter, short of economists’ expectations of 3.1%, and down from the previous quarter’s 3% reading.

• Officials in south-west Washington were able to salvage almost 500 damaged ballots from a ballot box that was set on fire on Monday in what officials have called an attack on democracy. An unknown number of ballots were destroyed when someone placed incendiary devices in a drop box in Vancouver, Washington, while three ballots were damaged in a fire at a box in nearby Portland, Oregon. Those fires and one other are linked, officials have said.

Investing in technology companies involves weighing up expected quantities of jam today, jam tomorrow and jam at some unknown future date. Facebook parent Meta Platforms and Microsoft are serving up just enough of each.

Both reported earnings on Wednesday that — like Google parent Alphabet the previous day — outpaced what analysts expected. Microsoft’s cloud computing business increased revenue by 22 per cent, a little faster than the previous quarter. Meta’s sales of advertising increased by 19 per cent, and it exacted 11 per cent more per ad than a year earlier. Today’s jam, then, is safely taken care of.

Tomorrow is less certain. Since artificial intelligence mania took hold, quarterly earnings have become a kind of sanity check, whereby investors reassess how they feel about tech companies’ lavish investment plans. Steady share prices depend on corporate chiefs like Meta’s Mark Zuckerberg and Microsoft’s Satya Nadella walking a fine line between being bullish about AI’s potential and remaining credible about its financial returns.

On that front, the $1.5tn-valued Meta is in the more precarious position. It has told investors to brace for “significant acceleration” in capital expenditure next year. Spending is already double what it was three years ago, weighing in at a quarter of revenue. Like Microsoft, Meta is buying chips and servers, but where Microsoft in effect rents space in its cloud to clients, Meta’s is largely for its own use.

Meta’s other challenge is that, compared with some of its peers, its boldest prospects are relatively long-tailed. That makes it different from chipmaker Nvidia, say, which sells AI-enabling silicon for real money. Microsoft already has recurring revenue from corporate customers. Facebook, meanwhile, is building new products such as social network Threads, virtual assistants and AI-generated video ads with yet-to-be determined value.

Zuckerberg has at least read the room, and is making the case that AI will bring near-term pay-offs too. More than 1mn advertisers used Meta’s generative AI tools in the past month, for example, and the company thinks those tools make users 7 per cent more likely to click. Analysts have raised their forecasts for Meta’s revenue in 2026 by $30bn over the past year, to $210bn, according to LSEG.

As for the distant-future jam — such as the recently unveiled augmented-reality holographic glasses the company describes as “the next great leap” — investors aren’t putting much weight on that at all. Meta’s share price has risen 70 per cent this year, but that still implies almost $400bn of negative value for its far-out bets, Morgan Stanley analysts believe. Big ideas can drive big valuations, but only up to a point.

NEW YORK — A pig at an Oregon farm was found to have bird flu, the U.S. Department of Agriculture announced Wednesday. It’s the first time the virus has been detected in U.S. swine and raises concerns about bird flu’s potential to become a human threat.

The infection happened at a backyard farm in Crook County, in the center of the state, where different animals share water and are housed together. Last week, poultry at the farm were found to have the virus, and testing this week found that one of the farm’s five pigs had become infected.

The farm was put under quarantine and all five pigs were euthanized so additional testing could be done. It’s not a commercial farm, and U.S. agriculture officials said there is no concern about the safety of the nation’s pork supply.

But finding bird flu in a pig raises worries that the virus may be hitting a stepping stone to becoming a bigger threat to people, said Jennifer Nuzzo, a Brown University pandemic researcher.

Pigs can be infected with multiple types of flu, and the animals can play a role in making bird viruses better adapted to humans, she explained. The 2009 H1N1 flu pandemic had swine origins, Nuzzo noted.

“If we’re trying to stay ahead of this virus and prevent it from becoming a threat to the broader public, knowing if it’s in pigs is crucial,” Nuzzo said.

The USDA has conducted genetic tests on the farm’s poultry and has not seen any mutations that suggest the virus is gaining an increased ability to spread to people. That indicates the current risk to the public remains low, officials said.

A different strain of the bird flu virus has been reported in pigs outside the U.S. in the past, and it did not trigger a human pandemic.

“It isn’t a one-to-one relationship, where pigs get infected with viruses and they make pandemics,” said Troy Sutton, a Penn State researcher who studies flu viruses in animals.

This version of bird flu — known as Type A H5N1 — has been spreading widely in the U.S. among wild birds, poultry, cows and a number of other animals. Its persistence increases the chances that people will be exposed and potentially catch it, officials say.

It isn’t necessarily surprising that a pig infection was detected, given that so many other animals have had the virus, experts said.

The Oregon pig infection “is noteworthy, but does it change the calculation of the threat level? No it doesn’t,” Sutton said. If the virus starts spreading more widely among pigs and if there are ensuing human infections, “then we’re going to be more concerned.”

So far this year, nearly 40 human cases have been reported — in California, Colorado, Washington, Michigan, Texas and Missouri — with mostly mild symptoms, including eye redness, reported. All but one of the people had been to contact with infected animals.
