LONDON (AP) — Elon Musk said Friday that his plan to buy Twitter is “temporarily on hold” as he tries to pinpoint the exact number of spam and fake accounts on the social media platform, another twist amid signs of turmoil over the proposed $44 billion acquisition.

Musk has been vocal about his desire to clean up Twitter’s problem with “spam bots” that mimic real people and appeared to question whether the company was underreporting them.

In a tweet, the Tesla billionaire linked to a Reuters story from May 2 about a quarterly report from Twitter that estimated false or spam accounts made up fewer than 5% of the company’s “monetizable daily active users” in the first quarter.

“Twitter deal temporarily on hold pending details supporting calculation that spam/fake accounts do indeed represent less than 5% of users,” Musk said, indicating he’s skeptical that the number of inauthentic accounts is that low.

It wasn’t clear whether the issue could scuttle the deal. Musk later tweeted that he’s “still committed to acquisition.”

Neither Twitter nor Musk responded early Friday to requests for comment.

The issue of fake accounts on Twitter is not secret.

In its quarterly filing with the SEC, even Twitter doubted that its count of bot accounts was correct, conceding that the estimate may be low. “In making this determination, we applied significant judgment, so our estimation of false or spam accounts may not accurately represent the actual number of such accounts, and the actual number of false or spam accounts could be higher than we have estimated,” the filing says.

A review of Twitter filings with the U.S. Securities and Exchange Commission shows that the estimate of spam bot accounts and similar language expressing doubts about it have been in Twitter’s quarterly and annual reports for at least two years, well before Musk made his offer and it would have been known to him and his advisors.

Stock in both Twitter and Tesla swung sharply in opposite directions Friday, with Twitter’s stock falling nearly 6% and shares of Tesla, which Musk had proposed using to help fund the Twitter deal, jumping nearly 7% in trading before the opening bell.

Investors have had to weigh legal troubles for Musk, as well as the possibility that acquiring Twitter could be a distraction from running the world’s most valuable automaker. The proposed deal continued to pressure shares of Tesla, which had already fallen 16% this week.

The sharp jump in the price of Tesla shares before the opening bell Friday singled rising doubts that the acquisition of Twitter will take place.

Musk has already sold off more than $8 billion worth of his Tesla shares to finance the purchase.

Originally Musk had committed to borrowing $12.5 billion with Tesla stock as collateral to buy Twitter. He also would borrow $13 billion from banks and put up $21 billion in Tesla equity.

Last week, Musk strengthened the equity stake in his offer for Twitter with commitments of more than $7 billion from a diverse group of investors including Silicon Valley heavy hitters like Oracle co-founder Larry Ellison.

Money from the new investors cuts the amount borrowed on the value of Tesla stock to $6.25 billion, according to the filing. The Tesla equity share could go from $21 billion to $27.25 billion.

Wedbush analyst Dan Ives, who follows both Tesla and Twitter, said Musk’s “bizarre” tweet will lead Wall Street to either think the deal is likely falling apart, Musk is attempting to negotiate a lower deal price, or he is simply walking away from the deal with a $1 billion penalty.

“Many will view this as Musk using this Twitter filing/spam accounts as a way to get out of this deal in a vastly changing market,” Ives wrote.

He added that the Musk’s use of Twitter rather than a financial filing to make the announcement was troubling and “sends this whole deal into a circus show with many questions and no concrete answers as to the path of this deal going forward.”

Musk’s tweet comes a day after the social media company fired two of its top managers. Twitter said the company is pausing most hiring, except for critical roles, and is “pulling back on non-labor costs to ensure we are being responsible and efficient.”

In a memo sent to employees and confirmed by Twitter, CEO Parag Agrawal said the company has not hit growth and revenue milestones after the company began to invest “aggressively” to expand its user base and revenue.

SEOUL, South Korea (AP) — North Korea imposed a nationwide lockdown Thursday to control its first acknowledged COVID-19 outbreak after holding for more than two years to a widely doubted claim of a perfect record keeping out the virus that has spread to nearly every place in the world.

The outbreak forced leader Kim Jong Un to wear a mask in public, likely for the first time since the start of the pandemic, but the scale of transmissions inside North Korea wasn’t immediately known. A failure to slow infections could have serious consequences because the country has a poor health care system and its 26 million people are believed to be mostly unvaccinated. Some experts say North Korea, by its rare admission of an outbreak, may be seeking outside aid.

However, hours after North Korea confirmed the outbreak, South Korea’s military said it detected the North had fired three suspected ballistic missiles toward the sea. It was its 16th round of missile launches this year, in brinkmanship aimed at forcing the United States to accept North Korea as a nuclear power and negotiate sanctions relief and other concessions from a position of strength.

The official Korean Central News Agency said tests of virus samples collected Sunday from an unspecified number of people with fevers in the capital, Pyongyang, confirmed they were infected with the omicron variant.

In response, Kim called at a ruling party Politburo meeting for a thorough lockdown of cities and counties and said workplaces should be isolated by units to block the virus from spreading. He urged health workers to step up disinfection efforts at workplaces and homes and mobilize reserve medical supplies.

Kim said it was crucial to control transmissions and eliminate the infection source as fast as possible, while also easing inconveniences to the public caused by the virus controls. He insisted the country will overcome the outbreak because its government and people are “united as one.”

Despite the elevated virus response, Kim ordered officials to push ahead with scheduled construction, agricultural development and other state projects while bolstering the country’s defense posture to avoid any security vacuum.

North Korea’s state TV showed Kim and other senior officials wearing masks as they entered a meeting room, although Kim removed his mask to speak into a set of microphones. Still photos distributed by KNCA showed Kim unmasked and sitting at the head of a table where all other officials remained masked.

South Korea’s Unification Ministry, which handles inter-Korean affairs, couldn’t immediately confirm whether it was the first time state media showed Kim wearing a mask since the start of the pandemic. Kim has previously spoken to huge crowds without a mask as he praised the country’s earlier pandemic response, and his decision to be seen with a mask could be aimed at raising public vigilance.

North Korea, which has maintained strict anti-virus controls at its borders for more than two years, didn’t provide further details about its new lockdown. But an Associated Press photographer on the South Korean side of the border saw dozens of people working in fields or walking on footpaths at a North Korean border town — an indication the lockdown doesn’t require people to stay home, or it exempts farm work.

The measures described in state media and Kim’s declaration that economic goals should still be met could indicate that North Korea is focusing more on restricting travel and supplies between regions, analyst Cheong Seong-Chang at South Korea’s Sejong Institute said.

North Korea’s government has shunned vaccines offered by the U.N.-backed COVAX distribution program, possibly because they have international monitoring requirements.

Seoul’s Unification Ministry said South Korea is willing to provide medical assistance and other help to North Korea based on humanitarian considerations. Relations between the Koreas have deteriorated since 2019 amid a stalemate in nuclear negotiations and the North’s increasingly provocative weapons tests.

In Beijing, Chinese Foreign Ministry spokesperson Zhao Lijian said Beijing is offering North Korea help in dealing with the outbreak. North Korea has reportedly rejected previous Chinese offers of domestically developed vaccines.

Kim Sin-gon, a professor at Seoul’s Korea University College of Medicine, said North Korea is likely signaling its willingness to receive outside vaccines, but wants many more doses than offered by COVAX to inoculate its entire population multiple times. He said North Korea would also want COVID-19 medicines and medical equipment shipments that are banned by U.N. sanctions.

Omicron spreads much more easily than earlier variants of the coronavirus, and its fatality and hospitalization rates are high among unvaccinated older people or those with existing health problems. That means the outbreak could cause “a serious situation” because North Korea lacks medical equipment and medicine to treat virus patients and many of its people are not well-nourished, Kim Sin-gon said.

Ahn Kyung-su, head of DPRKHEALTH.ORG, a website focusing on health issues in North Korea, said North Korea’s admission of the outbreak is likely designed to press its people harder to guard against the virus as China, which shares a long, porous border with the North, has placed many of its cities under lockdown over virus concerns.

North Korea will also likely stress lockdowns, although the experience of China’s “zero-COVID” policy suggests that approach doesn’t work against the fast-moving omicron variant, said Leif-Eric Easley, a professor of international studies at Seoul’s Ewha Womans University.

“For Pyongyang to publicly admit omicron cases, the public health situation must be serious,” Easley said. “This does not mean North Korea is suddenly going to be open to humanitarian assistance and take a more conciliatory line toward Washington and Seoul. But the Kim regime’s domestic audience may be less interested in nuclear or missile tests when the urgent threat involves coronavirus rather than a foreign military.”

North Korea’s previous coronavirus-free claim had been disputed by many foreign experts. But South Korean officials have said North Korea had likely avoided a huge outbreak, in part because it instituted strict virus controls almost from the start of the pandemic.

Early in 2020 — before the coronavirus spread around the world — North Korea took severe steps to keep out the virus and described them as a matter of “national existence.” It all but halted cross-border traffic and trade for two years, and is even believed to have ordered troops to shoot on sight any trespassers who crossed its borders.

The extreme border closures further shocked an economy already damaged by decades of mismanagement and U.S.-led sanctions over its nuclear weapons and missile program, pushing Kim to perhaps the toughest moment of his rule since he took power in 2011.

North Korea had been one of the last places in the world without an acknowledged COVID-19 case after the virus first detected in the central Chinese city of Wuhan in late 2019 spread to every continent including Antarctica. Turkmenistan, a similarly secretive and authoritarian nation in Central Asia, has reported no cases to the World Health Organization, though its claim also is widely doubted by outside experts.

In recent months, some Pacific island nations that kept the virus out by their geographic isolation have recorded outbreaks. Only tiny Tuvalu, with a population around 12,000, has escaped the virus so far, while a few other nations – Nauru, Micronesia and Marshall Islands – have stopped cases at their borders and avoided community outbreaks.

North Korea’s outbreak comes as China — its close ally and trading partner — battles its biggest outbreak of the pandemic.

In January, North Korea tentatively reopened railroad freight traffic between its border town of Sinuiju and China’s Dandong for the first time in two years, but China halted the trade last month due to an outbreak in Liaoning province, which borders North Korea.

WASHINGTON (AP) — Inflation slowed in April after seven months of relentless gains, a tentative sign that price increases may be peaking while still imposing a financial strain on American households.

Consumer prices jumped 8.3% last month from 12 months earlier, the Labor Department said Wednesday. That was below the 8.5% year-over-year surge in March, which was the highest rate since 1981.

On a month-to-month basis, prices rose 0.3% from March to April, a still-elevated rate but the smallest increase in eight months. Consumer prices had spiked 1.2% from February to March, mostly because of a sudden jump in gas prices triggered by Russia’s invasion of Ukraine.

Nationally, the price of a gallon of regular gas has reached a record $4.40, according to AAA, though that figure isn’t adjusted for inflation. The high price of oil is the main factor. A barrel of U.S. benchmark crude sold for around $100 a barrel Tuesday. Gas had fallen to about $4.10 a gallon in April, after reaching $4.32 in March.

Beyond the financial strain for households, inflation is posing a serious political problem for President Joe Biden and congressional Democrats in the midterm election season, with Republicans arguing that Biden’s $1.9 trillion financial support package last March overheated the economy by flooding it with stimulus checks, enhanced unemployment aid and child tax credit payments.

On Tuesday, Biden sought to take the initiative and declared inflation “the No. 1 problem facing families today” and “my top domestic priority.”

Biden blamed chronic supply chain snarls related to the swift economic rebound from the pandemic, as well as Russia’s invasion of Ukraine, for igniting inflation. He said his administration will help ease price increases by shrinking the government’s budget deficit and by fostering competition in industries, like meatpacking, that are dominated by a few industry giants.

Still, new disruptions overseas or other unforeseen problems could always send U.S. inflation back up to new highs. If the European Union decides, for example, to cut off Russian oil, gas prices in the United States would likely accelerate. China’s COVID lockdowns are worsening supply problems and hurting growth in the world’s second-biggest economy.

Previous signs that U.S. inflation might be peaking didn’t last. Price increases decelerated last August and September, suggesting at the time that higher inflation might be temporary, as many economists — and officials at the Federal Reserve — had suggested. But prices shot up again in October, prompting Fed Chair Jerome Powell to start shifting policy toward higher rates.

This time, though, several factors are pointing to an inflation peak. Natural gas prices, which soared in March after Russia’s invasion of Ukraine, fell on average in April and likely slowed inflation. Used car prices are also expected to have dropped last month. Automakers’ supply chains have unraveled a bit, and new car sales have risen.

While food and energy have endured some the worst price spikes of the past year, analysts often monitor the core figure to get a sense of underlying inflation. Core inflation also typically rises more slowly than the overall price increases and can take longer to decline. Rents, for example, are rising at a historically fast pace, and there is little sign of that trend reversing anytime soon.

The unexpected persistence of high inflation has caused the Fed to embark on what may become its fastest series of interest rate increases in 33 years. Last week, the Fed raised its benchmark short-term rate by a half-point, its steepest increase in two decades. And Powell signaled that more such sharp rate hikes are coming.

The Powell Fed is seeking to pull off the notoriously difficult — and risky — task of cooling the economy enough to slow inflation without causing a recession. Economists say such an outcome is possible but unlikely with inflation this high.

In the meantime, by some measures Americans’ wages are rising at the fastest pace in 20 years. Their higher pay enables more people to at least partly keep up with higher prices. But employers typically respond by charging customers more to cover their higher labor costs, which, in turn, heightens inflationary pressures.

Last Friday’s jobs report for April included data on hourly pay that suggested that wage gains were slowing, which, if it continues, could help ease inflation this year.
