Graham Platner has not formally ended his campaign for a Senate seat in Maine, but top Democrats believe it’s only a matter of time, after an accusation of rape spurred disapproval so widespread that it effectively tanked his chances of winning.

Platner, who denies the accusation, won the party’s primary less than a month ago in a race that could help decide which party controls Congress. This afternoon, Senator Bernie Sanders of Vermont, one of Platner’s earliest and most prominent backers, joined the chorus of Democrats across the ideological spectrum urging him to quit before the July 13 deadline. “In light of these very serious allegations,” Sanders said, “I have recommended that he step aside.”

In the meantime, progressives and moderates are battling over who should take Platner’s place. On a private call last night, during which he implied that a decision to withdraw would be forthcoming, Platner said that he believed he could help sway who his replacement might be. If Platner does agree to step down by Monday, Democrats would have until July 27 to choose a new nominee. The party could hold a convention or caucus in Maine later this month, or find a different way to pick a candidate.

Already a number of names have emerged as potential contenders. Those include Troy Jackson, a former president of the Maine Senate; Nirav Shah, a former director of Maine’s public health agency; and Shenna Bellows, Maine’s secretary of state.

The U.S. attacks Iran and revokes its oil waiver

The Trump administration rescinded a waiver allowing Iran to produce, sell and deliver oil after three tankers were attacked in the Strait of Hormuz. The exemption, which the U.S. granted in last month’s cease-fire deal, could have helped boost Iran’s economy.

Then, this afternoon, the U.S. military said it was carrying out airstrikes in Iran “to impose heavy costs for targeting and attacking commercial shipping.” Here’s the latest.

U.S. obesity rates decline as usage of weight-loss drugs soar

In a new national survey, a record 11 percent of Americans said they were currently taking a weight-loss drug. That’s a huge jump from the 3 percent who reported taking one in 2024, a sign that lower prices and positive results have elevated the drugs.

Poll data also showed that the percentage of Americans who are obese is falling, from 39.9 percent in 2022 to 36.4 this year. And rates of diabetes diagnoses are now steady, after climbing for over a decade.

Russia’s Olympics ban is lifted

The International Olympic Committee announced today that it was ending the suspension imposed on Russia after its invasion of Ukraine. The move clears the way for Russia to send a team to the 2028 Summer Olympics in Los Angeles.

The committee said that the decision had been applied “provisionally,” subject to future Russian conduct, and that a decision had not yet been made on whether to allow the Russian flag or anthem to be used.

How to be a good dinner guest

There’s no shortage of tips for people planning a party, but much less attention is paid to the art of being a guest. So, we asked a number of dinner party veterans for some advice. They recommended being on time, but never early; skipping the goodbye, but sending a thank you card; and much more.

That effort is part of our style magazine’s summer entertaining issue. Also included are dispatches from carefully planned soirees in Minorca and Bangkok, as well as a guide to making vibrant paper flowers.

These space rocks were spotted hugging each other

An uncrewed Japanese spacecraft named Hayabusa2 has been exploring the cosmos for more than a decade. Two days ago, it zipped past an asteroid at 11,000 miles per hour and snapped the photo above.

It turns out, the asteroid — named Torifune — is actually a pair of conjoined space rocks that somehow managed to collide so gradually and peacefully that, instead of exploding, they fused together. “Yeah, that’s weird,” one planetary scientist said after seeing the image.

Have a gentle evening.
