The NYPD says a letter with a suspicious white powder in it was sent to the law office of a man who was behind a racist rant that went viral last week.

Police say officers who responded to 275 Madison Avenue at around 3:25 p.m. Thursday were met by two women who said they opened a envelope addressed to Aaron Schlossberg that had a white powdery substance in it.

EMS evacuated the floor, according to police.

Authorities say the two women displayed no symptoms. They are being evaluated by EMS workers.

It is unclear if Schlossberg was in the office at the time. A letter posted outside his office last week said he was no longer allowed in the building.

A rant by Schlossberg went viral on social media last week. In it, he can be heard yelling at Spanish-speaking employees, threatening to call immigration officials on them.

Schlossberg has since apologized.
