An influential city pastor demanded on Sunday that Mayor de Blasio fire the cop who placed Eric Garner in the chokehold that led to his death — before Donald Trump’s new attorney general takes office.

The Rev. Calvin Butts explained time was essential.

“Before the new administration is sworn in, we have one priority for our mayor: the immediate termination of NYPD Officer Daniel Pantaleo,” Butts said to his congregation at Abyssinian Baptist Church in Harlem. “Pantaleo, who killed Eric Garner, is still a New York City police officer.”
