The letter was reportedly addressed to Donald Trump Jr., her husband, and she had opened it. Trump was said to open the letter with the mysterious, suspicious substance around 10 A.M. "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.

Three patients from the household were transported to hospital for further evaluation, said Fire Department spokeswoman Sophia Kim.
