Donald Trump Jr.‘s wife, Vanessa Trump, was taken to hospital on Monday after being exposed to an unidentified white powder that was mailed to the family’s Manhattan home.
City officials told NBC News that the letter was addressed to her husband, who is the eldest son of U.S. President Donald Trump.
The New York Police Department confirmed that the package was opened by the wife who then called 911. Vanessa, along with two other people who were inside the home, were taken to New York Presbyterian Weill Cornell Medical Center after she complained of nausea.

Police said there is no evidence that the powder was harmful, but detectives are investigating.
The president’s personal attorney, Michael Cohen, released a statement on the incident Monday afternoon.
“How disturbed must a person be to do what they did to a mother of five children?” the statement to NBC News read. “This dangerous and reckless act goes beyond political differences.”

Ivanka Trump also wished her sister-in-law well on Twitter, writing “no one deserves to be frightened this way.”
U.S. authorities have been on alert for mail with white powder in it since 2001, when envelopes laced with anthrax were sent to media outlets and U.S. lawmakers, killing five people.
In 2016, the president’s other son, Eric Trump, was also sent white powder in the mail. It was later deemed harmless.
