President Trump sent social media abuzz with a cryptic image of a mysterious blonde woman late Saturday, which he captioned “Great daughter.”

Many observers pointed out that the woman in the photo is Margo Catsimatidis, taken in the 1990s or early 2000s, but it’s not entirely clear why Trump decided to post a photo of her in that way.

“Great daughter. My Honor!!!” Trump wrote on Truth Social next to an image of Margo.

Her husband, John Catsimatidis, is a billionaire New York City businessman and talk radio host. He is the CEO of Gristedes grocery chains and the Red Apple Group. The family is famously close with Trump and a key donor to the president.

Margo and Cats’ daughter, Andrea, has led the Manhattan Republican Party for nearly a decade. She is a staunch backer of the president and close ally.

The photo is thought to show Margo during a visit to Camp David under the Clinton administration. The woman in the image is sitting on a red couch and speaking on the phone to someone.

Camp David had red couches decades ago. Margo played a key role in building Evergreen Chapel at the presidential retreat, according to her website.

She is also known to have been friendly with the Clintons years ago.

Trump arrived at Camp David, the presidential retreat in Maryland, Saturday evening as Vice President JD Vance leads negotiations with Iran during his trip to Switzerland.

Trump’s visit to Camp David comes amid Vance’s sensitive negotiations with Iran — the first round of talks with the Islamic Republic under the memorandum of understanding, which was signed electronically last week.

The MOU had laid out a framework for a peace deal, but now the two sides are trying to iron out a full-fledged one.

The president told Fox News chief foreign correspondent Trey Yingst that the MOU is a “60-day option” and stressed that he “can do whatever I want” afterward. The president claims to have spoken with Iranian officials overnight.

He also threatened Iran if the regime tries to close down the Strait of Hormuz again, where roughly a fifth of the world’s seaborne oil supplies once flowed through annually.

“You close it, and you won’t have a country,” Trump told Yingst about his message to Iran. “You won’t even make it back to your f—ing country.”
