NEW YORK — New York Mayor Bill de Blasio said Wednesday that the city will paint a Black Lives Matter mural in front of Trump Tower on Fifth Avenue soon —and the president hit back at what he called a wasteful “symbol of hate.”

“(Trump) will get a message that he still doesn’t understand,” de Blasio said on MSNBC’s “Morning Joe.” “Maybe seeing it outside his doorstep will help him get the point.”

The mayor said the mural would be created as a matter of urgency.

“That is going to be (completed) in a matter of days,” de Blasio told host Joe Scarborough.

Trump wasted little time attacking the plan. He denounced the planned Black Lives Matter mural as a “symbol of hate,” and said it would amount to “denigrating this luxury Avenue.”

Trump tied the mural, which he called “expensive,” to the city’s push to cut funding for the New York Police Department in response to the racial justice protests.

The city has not said how much the mural would cost, but it is certainly a tiny fraction of any cut in the NYPD budget.

The mayor shot back by claiming that Trump’s criticism of Black Lives Matter is “the definition of racism.”

“Black people BUILT 5th Ave and so much of this nation,” de Blasio tweeted. “Your “luxury” came from THEIR labor.”

Artists painted a similar mural on Fulton Street in the Bedford-Stuyvesant section of Brooklyn, with the city’s blessing. It was modeled after a similar work of street art in Washington, D.C., near the White House.

De Blasio had already vowed to create the mural on Fifth Avenue, between 57th and 56th streets, as a way of tweaking Trump for his botched response to the racial justice protests sweeping the nation since the police killing of George Floyd last month.

Trump has come under harsh criticism for his response to the protests. Even though he criticized the killing of Floyd, he denounced the Black Lives Matter movement as being controlled by Democrats, anarchists and so-called antifa radicals.
