A package containing "suspicious white powder" was discovered at noon on Friday in the building where a grand jury has been hearing evidence in the Trump "hush-money" investigation led by Manhattan District Attorney Alvin Bragg, officials told Insider.
The package was delivered to the building's mail room, and was non-hazardous, police told Insider.
The package was delivered by USPS, Fox News reported; the New York Post reported that it was an envelope addressed to "Alvin."
The grand jury meets Mondays, Wednesdays and Thursdays, sources have told Insider, and was not in session on Friday.
No one was sickened or taken to the hospital; the package was determined to be non-hazardous within three hours, officials told Insider.
