NEW YORK--U.S. President Donald Trump's daughter-in-law Vanessa Trump was taken to a New York hospital on Monday after she opened a piece of mail containing an unidentified white powder that was later determined to be non-hazardous, officials said.
Vanessa Trump, the wife of the president's eldest son Donald Jr., was hospitalized after she complained of nausea following her exposure, New York officials said. Two other people who were present were also taken to the hospital.
"The substance had arrived by mail and it was addressed to Donald Trump Jr.," said New York Police Department spokesman Carlos Nieves.
U.S. authorities have been on alert for mail containing white powder since 2001, when envelopes laced with anthrax were sent to media outlets and U.S. lawmakers, killing five people. Three patients from the household were transported to the NewYork-Presbyterian/Weill Cornell Medical Center for further evaluation, said Fire Department spokeswoman Sophia Kim.
The three included Vanessa Trump's mother, although she had not complained of symptoms, the police spokesman said.
The package had a Boston postmark, ABC News and the New York Post reported, citing unnamed law enforcement sources. NYPD officials declined to comment on that detail.
"Thankful that Vanessa & my children are safe and unharmed after the incredibly scary situation that occurred this morning," Trump Jr. said on Twitter. "Truly disgusting that certain individuals choose to express their opposing views with such disturbing behavior."
The U.S. Secret Service, which is charged with protecting members of the president's family, confirmed it was involved in the investigation, said spokesman Jeffrey Adams.
