As I describe on this site every year, one of the most important elements of Passover is to eat food that is not only kosher, but kosher for Passover. This means no leavened breads, no flour (except in certain limited circumstances, as in matzoh, where it is not allowed to rise and only bakes for 18 minutes), no corn or corn products, rice, beans, peas, stringbeans, and similar other restrictions. It’s very restrictive, but it’s a basic part of the Seder.
But not Obama’s stunt show seder.
In fact, as more proof it was a stunt, the Obama White House Seder was completely the opposite. Not only wasn’t it kosher for Passover. It wasn’t kosher, period
