Donald Trump Jr.’s wife Vanessa Trump has reportedly been hospitalized Monday after opening a letter containing a suspicious white powder.

Vanessa Trump was being examined at New York Presbyterian Weill Cornell Medical Center as a precaution, according to police.

The letter was addressed to Trump Jr., the eldest child of the president and his ex-wife Ivana.

“There is no indication anyone suffered any injuries and no sign that the substance was a hazardous material or a biological agent,” reports NBC News.

This is a developing story.
