U.S. says it struck Iranian drone and radar sites, as Iran claims attack on air base

01:39

The U.S. military said it carried out what it called self-defense strikes on Iranian radar and drone control sites over the weekend, while Tehran said it targeted an air base used in the U.S. attack.

U.S. Central Command said last night that the strikes had been carried out “in response to aggressive Iranian actions,” saying the country had shot down an American drone that was operating over international waters.

Iran’s Revolutionary Guards said today that its aerospace force had targeted the source of what it called a U.S. attack on a telecommunications tower. The IRGC said that if American attacks continued, its response would be “completely different” and Washington would be responsible for the consequences.

Meanwhile, a U.S. official said yesterday that Secretary of State Marco Rubio had spoken with Israeli Prime Minister Benjamin Netanyahu and Lebanese President Joseph Aoun as part of ongoing diplomatic negotiations.

Doctor in failed Tennessee execution says he didn’t want prisoner to suffer

Tennessee’s failure to execute a man by lethal injection last month after no one could locate a suitable vein led to a rare unmasking. Not only was a practicing physician identified as a participant in the death chamber, but witnesses say he played a direct role in botching the execution.

Dr. Mark Walton Fowler failed to set up a central venous line, an ordeal that left the prisoner, Tony Carruthers, crying out in pain after being punctured more than a dozen times, his lawyers said.

While questions remain about what went wrong, Fowler’s involvement has also reignited a larger ethical debate within the medical profession: Should doctors, whose job is to heal, play a part in executions?

Here’s what Fowler exclusively told NBC News in his first public comments since the failed execution.

Primary challengers threaten to unseat House members across the country

Incumbent members of Congress are notoriously difficult to defeat. But just a few months into primary season, four in the House have already lost re-election bids — and about a dozen more are facing legitimate threats.

The heaviest upcoming action will be on the Democratic side. In California’s primary tomorrow, incumbents such as Reps. Mike Thompson and Brad Sherman are up against energetic challengers arguing that voters want a fresh face, part of a national slate of candidates focused on generational change.

And other incumbents in states such as Colorado and Massachusetts face challenges from their party’s left flank, part of a running battle between progressives and the establishment.

More on Congress:

• Kentucky Gov. Andy Beshear said that “Texas is in play” for Democrats in this year’s Senate race after Ken Paxton’s GOP primary win.

• Amy Gertner, the wife of Democrat Graham Platner, said she is “really angry” about media reports that she previously told her husband’s Maine Senate campaign he had exchanged sexually explicit texts with other women, rather than focusing on the “real issues” her husband is running on.

High-end credit card perks are hurting shoppers who pay in cash

At a gas station in Virginia, managers expect to pay more in fees to credit card companies this year than they will on rent.

“It’s tougher for us to stay afloat,” said Maurice Lamarche, vice president of retail operations at Tiger Fuel Co. “It makes it harder for us to keep our prices low.”

As merchants are forced to pay more in credit card fees, which largely go toward funding rewards programs, the cost is often passed on to consumers in the form of higher prices. But the pain of those costs isn’t being felt equally.

For those paying with credit cards that offer rewards, higher prices are offset by things like cash back or points. Meanwhile, customers using cash or debit cards with no perks bear the brunt of costs — without receiving any benefits. The result is a $30 billion wealth transfer, a Harvard study estimated.

Chuck Schumer lays out plan to fight ‘anti-weaponization’ fund

Senate Minority Leader Chuck Schumer said today that Democrats would try to kill President Donald Trump’s $1.8 billion “anti-weaponization” fund, forcing Republicans to vote to preserve the compensation money.

“This week, Senate Democrats will launch a coordinated effort to kill the slush fund before one cent goes out the door,” Schumer said in a letter.

It’s unlikely that Democrats will be able to stop the fund in the Senate. They can, however, force Republicans to record their votes, offering a line of attack for Democrats in the upcoming midterms.

Additionally, Sens. Adam Schiff, Mark Kelly and Elissa Slotkin introduced a “Drain the Slush Fund Act,” which they said would “prevent taxpayer dollars” from being paid to Trump and his allies, including former Jan. 6 defendants.

Staff Pick: YouTubers are Hollywood’s new masters of horror

From the release of YouTuber Markiplier’s “Iron Lung” in February to Kane Parsons’ “Backrooms” last Friday, Hollywood appears to be increasingly turning to online creators with built-in fan bases to help boost the box office.

Horror historically has been a great launching pad for first-time filmmakers with tiny budgets. One recent example is Curry Baker’s “Obsession,” which was made for $750,000 and hit theaters earlier this month. The movie manages to make viewers feel every single cringey moment his main character goes through — kind of like watching your friend on the world’s worst (and most terrifying) date. That intimacy between viewer and creator is a through line in both horror movies and on platforms such as YouTube. It’s a natural fit.

Plus, newbie directors are a lot less risky if they’re coming with their own online following. One studio exec told me it “would be crazy” if Hollywood doesn’t pursue more projects like this, saying she’d already seen at least 20 spec scripts in this vein.
