New York Gov. Andrew Cuomo is under fire for declaring Wednesday that America “was never that great.”

The Democrat -- and rumored 2020 presidential candidate -- made the seemingly offhand remark as part of his rebuke of President Trump's "Make America Great Again" slogan during a bill-signing event in New York.

“We’re not going to make America great again. It was never that great,” Cuomo said, to an awkward blend of gasps and chuckles.

"We have not reached greatness, we will reach greatness when every American is fully engaged; we will reach greatness when discrimination and stereotyping against women, 51 percent of our population, is gone and every woman's full potential is realized and unleashed and every woman is making her full contribution," he continued.

In a statement, a Cuomo spokesperson tried walking the governor's remarks back.

The Governor believes America is great and that her full greatness will be fully realized when every man, woman, and child has full equality. America has not yet reached its maximum potential. When the President speaks about making America great again - going back in time - he ignores the pain so many endured and that we suffered from slavery, discrimination, segregation, sexism and marginalized women's contributions. The Governor believes that when everyone is fully included and everyone is contributing to their maximum potential, that is when America will achieve maximum greatness.

Republican New York gubernatorial candidate Marc Molinaro is now calling on Cuomo to apologize.

"America has always been great," Molinaro said on "Fox & Friends" on Thursday. "I was so ashamed and shocked that a man who has lived in privilege -- he was born on third base and thinks he hit a triple -- could think that America was never great."

He acknowledged that America has its imperfections, but he said its promise, purpose, principles and people have always been great.

"I'm ashamed to think my governor doesn't know that," Molinaro said. "He owes New Yorkers and the American people an apology."
