It’s not groundbreaking.

Mayor Bill de Blasio and President Trump don’t agree on much, but they both seem to like the same slogan.

Hizzoner appeared in front of a sign declaring “Promises Made, Promises Kept” at a groundbreaking for a new, 1000-seat school in East New York on Monday.

Trump and the GOP have repeatedly used the same slogan to tout the White House’s accomplishments.

Trump’s campaign posted a video on YouTube in September 2017 with the slogan and another on Facebook in July.

The president also appeared in front of signs with the popular slogan at a rally in Indiana in May.

City Hall spokesman Eric Phillips said he was not aware of the slogan-sharing, but added: “It’s not the most novel turn of phrase.”
