Nvidia investigates Huang as shares fall 5% in pre-market trading

Nvidia has placed chief executive Jensen Huang under an independent investigation following reports linking him to an alleged foreign intelligence operation. The reports concern a close relationship with a Chinese businesswoman accused of providing information to Beijing. Shares in the technology company fell 5% in pre-market trading.

The company's board said it had no reason to believe that Nvidia's confidential information or US national security had been compromised. Nevertheless, it said the investigation would review all available information. Republican lawmakers have requested that Huang brief the House foreign affairs and intelligence committees behind closed doors next week about the company's protections against foreign espionage.

Meanwhile, preparations for the Cop31 climate negotiations in Antalya, Turkey, come amid rising temperatures, extreme weather and international tensions. More than 90 national leaders and representatives from nearly 190 countries are expected to attend this week. Inflation fuelled by the US-Israel war on Iran adds to the difficult geopolitical backdrop.

The two-week conference will concentrate on putting emissions reduction commitments into practice and supporting people affected by the climate crisis. Australia is co-hosting the meeting with Turkey. Chris Bowen, Australia's climate and energy minister and the negotiations' president, told the Guardian: “We need a tangible outcome … that people can see is real.”

In the United States, Donald Trump signalled over the weekend that his administration could move further right following Republican losses in Tuesday's midterm elections. Democrats won control of both chambers of Congress, with voters rejecting policies including broad tariffs and the war with Iran.

Trump also acknowledged on Sunday that his deportation policy had been “too tough” and had hurt him politically. He offered to discuss an agreement with Democrats allowing some undocumented immigrants to stay. That overture came alongside his elevation of Stephen Miller, the architect of the immigration crackdown, to White House chief of staff.

Democratic leaders said they were still developing their congressional strategy, with investigations and legislation expected to feature prominently. Hakeem Jeffries, who is expected to become House speaker, expressed strong support for impeaching defense secretary Pete Hegseth. Departing Republican representative Thomas Massie has also sought to revive his impeachment effort against Hegseth.

In Poland, police said on Monday that the suspect in Saturday's Kraków market square shooting had died in hospital. Six people were killed and 16 injured in the attack. The 24-year-old suspect, whom authorities believe was probably influenced by far-right ideologies, had been critically wounded during a shootout with police. Prosecutors opened a terrorism investigation.

In Israel, former military chief Gadi Eisenkot began efforts to assemble a government by approaching allies of Benjamin Netanyahu. President Isaac Herzog gave Eisenkot, 66, a 28-day mandate to form a government, although his bloc does not hold a majority. Eisenkot accused Netanyahu of bringing Israel to a historic crisis.
