President Trump allegedly did not attend White House Passover Seder

The annual White House Passover Seder was held on Monday night, the Washington Post reports. It was started by Jewish staffers and then-President Obama during his administration.

In a statement to the Post, White House spokeswoman Natalie Strom confirmed that the tradition began under Obama for staffers who were far from home for the holiday. It began even before he was president: in 2008, aides organized a Seder on the campaign trail -- and Obama himself attended.

The Trump White House changed the tradition up this year. "We'll also be opening it up for interested WH staff (Jewish and non-Jewish alike) to take part in a Seder on campus," Storm wrote to the Post.

Storm also noted that it was unlikely that Trump himself would go. "A few details are still being nailed down but as of now it seems the President will not be attending," she said.

On Monday, Press Secretary Sean Spicer tweeted a photo of the dinner:

Huffington Post reporter Christina Wilkie was quick to comment that neither Trump nor Ivanka Trump and son-in-law Jared Kushner were in attendance. Kushner is Jewish and Ivanka converted to Judaism.

According to the Washington Post, Trump is the first president with Jewish members of his immediate family. It remains unknown what the first family's Seder plans were, if any. Ivanka Trump, though, did share a photo in acknowledgment of the holiday:

She wrote, "During Passover, we reflect on the significance of the exodus from Egypt and celebrate the great freedoms we enjoy today!"

The president also tweeted out a Happy Passover on Monday:

"Happy Passover to everyone celebrating in the United States of America, Israel, and around the world," the president said.
