NEW YORK (WABC) -- New York City Mayor Bill de Blasio grabbed a roller Thursday to help paint "Black Lives Matter" in front of Trump Tower on Fifth Avenue.
De Blasio was flanked by his wife, Chirlane McCray, and the Rev. Al Sharpton as they helped paint the racial justice rallying cry in giant yellow letters as activists chanted, "Whose streets? Our streets!"
"When we say 'Black Lives Matter,' there is no more American statement, there is no more patriotic statement because there is no America without Black America," de Blasio said. "We are acknowledging the truth of ourselves as Americans by saying 'Black Lives Matter.' We are righting a wrong."
President Donald Trump has referred to the Black Lives Matter murals as a symbol of hate, tweeting the sign would denigrate Fifth Avenue.
"What it says is America is towering over hate," Brooklyn Borough President Eric Adams said.
The Naked Cowboy, a Trump supporter, galloped up from Times Square to say he supports the Black Lives Matter message, but not the mayor's decision to the mural in right front of Trump Tower.
"The symbolism is awesome, and if he was trying to say we can do this (together) it would've been the greatest event that ever happened," he said. "But it's not what happened. It's kind of petty."
At Foley Square Thursday morning, City Council members gathered at a different Black Lives Matter mural to unveil the co-naming of the street to Black Lives Matter Boulevard.
"To tweak him, and anger him, and insult him, which is exactly what he does, it has to be done," participant Paul Rossen said.
De Blasio says the murals are to honor members of the black community who helped build New York, and members of the movement taking part in the painting hope the message lasts long after the paint dries.
"Black lives do matter, and I hope it's not just something written on street and driven over," participant Amber Fairweather said.
As more murals pop up across New York City, a Black Lives Matter mural was unveiled in Harlem on Wednesday morning.
The big, bold letters were drawn on Adam Clayton Powell Boulevard between 125th and 127th streets. It was painted by local artists and community group members.
The mayor has pledged to paint multiple Black Lives Matter murals across the city. There are currently two other murals in Brooklyn and one on Staten Island.
