President Trump accused Mayor Bill de Blasio of ripping off his campaign slogan, saying “that’s not at all nice.”

“Bill DeBlasio, the high taxing Mayor of NYC, just stole my campaign slogan: PROMISES MADE PROMISES KEPT! That’s not at all nice. No imagination!,” Trump wrote on Twitter Tuesday.

The mayor quickly hit back on Twitter.

“The difference is that I’m not lying when I say it,” he wrote.

At a groundbreaking for a new school in East New York on Monday, Hizzoner stood in front of a “Promises Made, Promises Kept” banner.

Trump has used the same slogan at campaign-style rallies to tout his administration’s accomplishments.

City Hall spokesman Eric Phillips denied pillaging the tagline when he was asked about the similarity by a Post reporter on Monday.

“It’s not the most novel turn of phrase,” he said.
