President Donald Trump has signed a new executive order on oversight of artificial intelligence, less than two weeks after postponing a White House ceremony over his concerns that a similar policy could dull America’s edge on AI technology.

It was not immediately clear to what extent the order signed Tuesday differed from the one he declined to sign on May 21. The order establishes a framework to vet the national security risks of the most advanced AI systems for up to a month before their public release.

US sanctions Iran’s Nobitex and 3 others

The Trump administration has placed sanctions on Iran’s largest digital asset exchange, Nobitex, and three others.

This move is part of ongoing efforts to pressure Iran into a deal to end a war with the U.S. and Israel. Treasury says Nobitex processed over 50% of Iran’s digital asset income last year and supports sanctions evasion.

Santos reported over suspicious Kalshi trades

A prediction market reported U.S. Rep. George Santos to federal prosecutors after he boasted he’d be going to President Donald Trump’s State of the Union address, then bet against his own attendance. That’s according to a person familiar with the investigation who spoke to The Associated Press on condition of anonymity.

The prediction marketplace Kalshi detected trades made by Santos ahead of Trump’s Feb. 24 speech. Santos had said he would attend the speech, but did not show up.

Trump is facing a new inflation warning

The world is getting more uptight about lending money to President Donald Trump’s government. The energy price spike triggered by the Iran war has seeped into the price of bonds that help fund the U.S. government.

That’s caused interest rates to climb in ways that are worsening affordability pressures, creating a new risk for Republicans in November’s elections. Trump says a task force on fraud could find enough savings to balance the budget. Economists say that’s probably unrealistic because of the magnitude of the deficit.

Wall Street inches to more records

The U.S. stock market inched to more records as winners of the artificial-intelligence boom kept driving higher.

The S&P 500 rose 0.1% Tuesday. The Dow Jones Industrial Average added 0.4%, and the Nasdaq composite edged up by less than 0.1%. All three indexes set all-time highs. Marvell Technology leaped to its biggest gain ever after Nvidia’s CEO suggested it could be the next company to be worth $1 trillion.

Trump administration proposes tariffs on Brazil

The Trump administration proposed 25% tariffs on imports from Brazil, charging that the world’s 10th-biggest economy engages in trade practices that are “unreasonable” and that “burden or restrict U.S. commerce.”

The announcement late Monday came after an investigation by the Office of the U.S. Trade Representative that charged Brazil with lax anti-corruption enforcement and unfair tariffs of its own, among other things.

Israel’s weapons exports reach a record high

Israel’s weapons exports reached a record high of over $19 billion last year, marking a 30% increase from 2024, according to Israel’s Defense Ministry. More than half of 2025’s sales were mega-deals valued at $100 million or more.

Sales have more than doubled in the last five years, despite criticism of Israel’s conduct in conflicts with Gaza, Hezbollah, and Iran. Experts say governments are drawn to Israel’s battle-tested weapons.
