Staff members who came into contact with the substance were isolated while emergency services tested the powder, spokesperson Al Baker said.
That amount includes the $354 million penalty against Trump and his company, as well as nearly $100 million in pre-judgment interest.
Engoran's verdict also bans Trump from operating a New York business for three years, jeopardizing Trump's role in his own business empire.

His top law clerk, Allison Greenfield, had also been the subject of numerous antisemitic and sexist threats from Trump supporters during the trial.
