AMNA NAWAZ: The day's other headlines start with President Trump's new tariffs on Brazil, and not just the what, but the why.

In announcing a 50 percent Levy on Brazilian imports, Trump cited what he called the witch-hunt against Brazil's former President, Jair Bolsonaro.

The populist leader is charged with trying to overturn his 2022 election loss.

Trump said today his trial -- quote -- "should end immediately," thereby tying the tariffs to Bolsonaro's legal fate.

That comes as the administration sent letters today informing seven other countries of new tariffs.

That's unless they can strike deals with the White House by August 1.

They include 30 percent levies on Algeria, Iraq, Libya and Sri Lanka, plus 25 percent on Brunei and Moldova and 20 percent on the Philippines.

Former President Joe Biden's White House doctor refused to answer questions from Republican lawmakers on Capitol Hill today.

Lawyers for Dr. Kevin O'Connor say he invoked his Fifth Amendment rights during a closed-door interview with the House Oversight Committee.

O'Connor also cited doctor-patient confidentiality.

Republican subpoenaed O'Connor last month as part of their investigation into Biden's health and mental fitness as president.

Biden has strongly denied that he was in any way impaired during his time in office, calling such claims ridiculous and false.

Measles cases in the U.S. are at their highest level in three decades.

That's according to CDC data out today showing 1,288 cases so far this year.

That compares to fewer than 300 cases for all of 2024.

At least three people have died and dozens have been hospitalized in outbreaks that began in undervaccinated communities in West Texas and nearby areas.

Experts say the measles vaccine is highly effective in preventing infection, but data show vaccination rates have dipped among children since the COVID-19 pandemic.

Turning overseas, Ukrainian officials say Russia launched its largest barrage of the war so far, sending more than 700 drones overnight.

Buildings burned through the morning in the northwestern city of Lutsk, a critical hub where Ukraine receives foreign military aid.

Officials say 10 other regions were also struck.

The barrage comes a day after President Trump criticized Russian President Vladimir Putin's ongoing aggression and follows a U-turn by the Trump administration on sending more military aid to Ukraine.

Meanwhile... VOLODYMYR ZELENSKYY, Ukrainian President: Good to see you.

How are you?

AMNA NAWAZ: In Rome, Ukrainian President Volodymyr Zelenskyy met with U.S. Special Envoy for Ukraine Keith Kellogg and earlier visited Pope Leo, who again offered to host peace talks at the Vatican.

Moscow had previously rejected that invitation.

Separately, Europe's top human rights court found that Russia committed widespread violations of international law in Ukraine dating back more than a decade.

That includes its role in the downing of Malaysia Airlines Flight 17 over separatist-controlled Ukraine in 2014; 298 people were killed in that crash.

The court also found Russia responsible in cases of murder, torture and sexual violence against Ukrainian civilians, as well as the kidnappings of Ukrainian children.

The Kremlin brushed off the court's ruling, saying it has -- quote -- "no intention to abide by it."

Southern New Mexico is bracing for more rain after monsoon conditions triggered flooding that killed at least three people.

WOMAN: Oh, my gosh.

Oh, no.

Oh, no.

AMNA NAWAZ: Raging waters gushed through the mountain village of Ruidoso late yesterday, at one point carrying an entire house downstream.

The local river rose nearly 19 feet in just minutes.

Officials say that a man, a 4-year-old girl and a 7-year-old boy were swept away.

Ruidoso's mayor said the situation could have been even worse, but most people heeded warnings to get to higher ground.

In Philadelphia, the city's largest workers union has reached a tentative deal to end a strike that had halted trash collection and other services.

Nearly 10,000 workers walked off the job on July 1, calling for better pay and benefits.

That included around 1,000 sanitation workers, meaning garbage was left to pile up in the streets.

In a social media post, Philadelphia's mayor said the strike is over, adding that the three-year contract would mean an overall pay raise of 14 percent over the mayor's four-year term.

Union president Greg Boulware told reporters he was not happy with the deal.

QUESTION: Why hasn't it ended if you aren't happy with the deal?

GREG BOULWARE, President, District Council 33: There was a lot of factors involved in what was going on, and we ultimately did what we thought was in the best interest of all of our membership.

The union stood up and fought for you and did the best we could to circumstances we had.

AMNA NAWAZ: The union also represents 911 dispatchers and water department workers.

The members still have to ratify the deal before it can take effect.

The CEO of social media platform X is stepping down after two years in the role.

Linda Yaccarino joined the company shortly after Elon Musk bought what was then Twitter in late 2022.

At the time, Musk said she would focus on running the company's business operations, leaving him to manage product design and tech matters.

Her departure comes a day after Musk's A.I.

chatbot called Grok posted antisemitic content in its responses to users.

Yaccarino did not provide a specific reason for her departure, and there's no word yet on a replacement.

On Wall Street today, stocks ended higher after A.I.

giant Nvidia became the first company in history to top $4 trillion in market value.

The Dow Jones industrial average added more than 200 points on the day.

The Nasdaq added nearly 200 points of its own.

The S&P 500 also closed in positive territory.
