Eric Trump, the son of President Trump, said Thursday every person in his family has had white powder mailed to them at their homes.

"I've been threatened. Don's been threatened. We've all had white powder show up at our house," Trump told Fox News host Sean Hannity.

Trump, who helps his older brother Donald Trump, Jr. manage the Trump Organization, did not specify incidents against himself or his other family members. The immediate Trump family includes Melania, Barron, Eric, Don Jr., Ivanka, and Tiffany.

In 2001, five people died after inhaling powdered anthrax spores mailed to the offices of media outlets and then-Sen. Tom Daschle, D-S.D., and Sen. Patrick Leahy, D-Vt. Seventeen other people were infected in the incident.

The only previously reported white powder incident since Trump took office occurred in February in New York City.

Vanessa Trump, the daughter-in-law to Trump and now ex-wife of Don Jr., was taken to the hospital after opening a suspicious letter that contained an unidentified white powdery substance.

The letter was addressed to her husband, Donald Jr., but Vanessa, as well as up to two others in the residence, were also taken to New York Presbyterian-Weill Cornell Medical Center in Manhattan in case they were exposed to toxic substances or biological materials.

Trump, 40, had said she felt ill after opening the item and called 911 Monday morning to report it. She told emergency responders she was coughing and felt nauseous.

Trump is the mother of five children.

New York Police Department officers said at the time a preliminary test of the substance suggested it was not toxic.
