Former President Donald Trump’s scheduled campaign trail appearance at a popular Brooklyn kosher deli was canceled Thursday after the owner died of a heart attack. He was 76.

Trump had been expected to stop by Gottlieb’s — a mom-and-pop restaurant known as a staple of Hasidic Williamsburg — before heading to Washington, DC, to speak at a “Combatting Antisemitism” event.

But the deli’s beloved owner Shalom Yoseph Gottelib — a dedicated dad and hardworking businessman, who often gave food to the needy — was hospitalized with pneumonia earlier this week and died after suffering cardiac problems Thursday, according to friends and religious leaders.

“Everybody’s in shock. He was a good person, and he was an icon because of the iconic restaurant he ran for a very long time,” said Rabbi Abe Friedman, a friend of Gottlieb. “Going from welcoming Trump to a funeral is quite shocking.”
