AMNA NAWAZ: In the day's other headlines: President Trump says he's raising tariffs next week to 25 percent on cars and trucks from the European Union, accusing the E.U.

of not complying with their trade deal.

The new levies come at a time when the global economy is already reeling from the Iran war.

Speaking to reporters at the White House, Mr.

Trump didn't elaborate on how he'd hike the tariffs or why he chose to do so now.

DONALD TRUMP, President of the United States: We raised the tariffs because they were not -- as usual, they were not adhering to the agreement that we have.

We have a trade deal with the European Union.

They were not adhering to it.

AMNA NAWAZ: Mr.

Trump was referring to a deal reached with the E.U.

last summer that set levies on most European goods at 15 percent.

The Supreme Court then ruled in February that much of his tariff agenda was illegal.

The Pentagon says it's made deals with seven major tech companies to use their A.I.

tools within the department's classified networks.

They include SpaceX, OpenAI, Google, Microsoft, and Nvidia, some of which already had deals with the Defense Department.

Officials say the companies will allow the Pentagon to employ their technology for any -- quote -- "lawful use."

That standard lies at the heart of a legal dispute involving Anthropic, which was not listed in today's announcement.

The A.I.

start-up has objected to its technology being used for fully autonomous weapons and domestic surveillance.

In Florida, a former Miami congressman with ties to Secretary of State Marco Rubio was convicted today of secretly lobbying for Venezuela.

A jury found David Rivera guilty on all counts, including failure to register as a foreign agent and conspiracy to commit money laundering.

The case centered on a $50 million lobbying campaign to convince the first Trump administration to ease sanctions on then-President Nicolas Maduro's government.

Rubio himself testified, though he's not been accused of any wrongdoing.

Rivera was taken into custody and faces around 10 years in prison.

In Texas, an investigation is under way into what caused a small plane to crash in the state's Hill Country, killing all five people on board.

The Cessna aircraft went down shortly before midnight last night in Wimberley, Texas, nearly 40 miles southwest of Austin.

An air traffic controller observed the plane moving erratically, and a nearby pilot says the plane emitted a distress signal before the crash.

The names of those on board have not yet been released, but a local pickleball club says they were members who were flying to a tournament.

In Washington state, police arrested a high school student suspected of wounding five people in a stabbing rampage.

The attack happened yesterday at Foss High School in Tacoma, just south of Seattle.

A police spokesperson says first responders were called after reports of a fight among students.

The campus briefly went into lockdown and classes were canceled for today.

Authorities say all the victims are now in stable condition, as well as the suspect, who was hospitalized with minor injuries.

Around the world, events have been taking place to mark May Day, also known as International Workers' Day, which honors the efforts of the global labor movement.

In Madrid, activists chanted "Long live the working class" and marched for collective bargaining in Seoul.

In Istanbul's Taksim Square, demonstrations turned violent.

Turkish police detained hundreds of protesters amid the clashes.

In many cases, rallies highlighted the ripple effects of the Iran war, like rising energy costs and commodity prices, as laid out by this protester in the Philippines.

MARY ANN CASTILLO, May One Movement (through translator): At first, you might think there's no connection.

But as we saw when the war in the Middle East broke out, crude oil and gasoline prices shot up.

There's a domino effect.

Prices increase across the board.

AMNA NAWAZ: Here in the U.S., May Day is not a public holiday, like it is in many other parts of the world, but cities including New York and Chicago saw marches and boycotts, where opposition to the policies of President Trump was a common theme.

On Wall Street today, stocks ended mixed following some strong corporate earnings.

The Dow Jones industrial average slipped about 150 points.

The Nasdaq rose more than 200 points, or nearly 1 percent.

The S&P 500 ended the week at a new all-time high.

And it's a case of lost and found with a Hollywood ending.

Lufthansa apologized to a Russian director today for briefly losing his Academy Award on a transatlantic flight.

Pavel Talankin and his co-director, David Borenstein, won the Oscar for their documentary "Mr.

Nobody Against Putin."

Borenstein posted on social media yesterday that TSA agents in New York told Talankin he couldn't bring his Oscar on board because it could be considered a weapon.

They sent it under the plane in a box instead.

After an international outcry, the airline said the statuette has been found and is being returned to its rightful owner.
