Vanessa Trump, the wife of Donald Trump Jr. and daughter-in-law of President Donald Trump, was hospitalized as a precaution Monday after opening an envelope that contained a white powder.
The letter was addressed to Donald Trump Jr., the President's eldest son.
A hazmat crew was called to the couple's Manhattan apartment and the police and Secret Service are investigating the incident.
"The Secret Service and our law enforcement partners in New York City are investigating a suspicious package addressed to one of our protectees received today in New York, New York. This is an active investigation and we cannot comment any further," the Secret Service said in a statement.
The NYPD deemed the substance to be non-hazardous but it was taken to a lab for further analysis.
