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.

The grand jury involved in the Trump case has been meeting in the building where the suspicious package was reported, but it does not sit on Fridays.

The grand jury was scheduled to meet Wednesday to hear from at least one additional witness in the case, but proceedings were canceled.

Two familiar sources told Fox News Digital on Wednesday that the grand jury was canceled amid “major dissension” within the district attorney’s office. One source claimed the district attorney is having trouble convincing the grand jury on potential charges due to the “weakness” of the case.

Trump has not been formally notified about whether Bragg actually plans to bring charges against him, according to sources familiar.
