Emergency personnel have responded after a package with suspicious white powder was delivered to the mail room for the New York City building housing the Manhattan District Attorney's office, according to police. 

A law enforcement source confirmed there was a note saying "Alvin – I’ll kill you" in the envelope. District Attorney Alvin Bragg is currently weighing whether to proceed with an indictment against former President Donald Trump for alleged hush money payments made to porn star Stormy Daniels in 2016.

The envelope delivered by the U.S. Postal Service Friday has been "deemed non-hazardous" at the scene, the mail room to the DA's office, officials told Fox News. 

Police responded to the scene shortly after 12 p.m., and as yet, no one has been ordered to evacuate.
