US President Donald Trump daughter-in-law  was taken to a hospital in New York City today after opening a package at her home that contained an unknown white powder, ABC News reported.

Vanessa Trump, 40, was examined at New York-Presbyterian Weill Cornell Medical Center as a precaution.

The suspicious letter was sent to Trump Jr.'s apartment in Manhattan this morning. It contained a note indicating the sender was angry, said the source, who did not elaborate.

Vanessa Trump and two other people at the apartment were decontaminated by firefighters at the scene before being taken to the hospital, according to police.

Preliminary tests show there was nothing harmful in the substance. There is no indication at this point that anyone suffered any injuries.
