"This is an active investigation and we can not comment any further", he said. After the envelope was opened, three people at the residence, including Vanessa, were taken to New York Presbyterian/Weill Cornell Medical Center strictly as a precaution.
Along with Vanessa Trump, two others, whose identities remained unknown, were hospitalized.
