DETROIT, Mich. — Mayor Bill de Blasio touted New York’s $15 minimum wage during Wednesday night’s Democratic debate — but a top aide for Gov. Andrew Cuomo wasn’t going to let him steal all the glory.

“When I became the mayor of the nation’s largest city I set us on a path of bold change,” de Blasio said during his opening statement. “They said it couldn’t be done but we gave pre-K to every child for free. We got rid of stop-and-frisk and we lowered crime. We raised the minimum wage to $15 an hour. Yes, it can be done.”

That statement sparked a fight over $15 — with Melissa DeRosa, secretary to Cuomo, snapping back.

“Since this is likely the last time he’ll likely be on stage, I’m going fact check: de Blasio had 0 to do with the statewide $15 min wage win…& raised min wage for NYC muni workers to $15 only AFTER statewide fast food workers & the cities of Rochester, Buffalo, and Syracuse,” DeRosa tweeted.

In response, de Blasio press secretary Freddi Goldstein tweeted a New York Times article titled: “Cuomo Rejects Another Plan by de Blasio: Minimum Wage.”

“As a reminder to all those keeping score,” Goldstein wrote.

DeRosa doubled down: “I repeat, de Blasio had less than 0 to do with the $15 minimum wage win.”
