An envelope addressed to Donald Trump Jr. and containing a white powdery substance was opened by his wife Monday morning, exposing her to the material and triggering a response by NYPD and Secret Service units, a police spokesman said.
Police later said the substance proved to be nontoxic.
The letter was addressed to Trump, the son of the president, at the apartment of his mother-in-law on East 54th Street where his wife, Vanessa, opened the envelope, the spokesman said.
Police units responded and while there was no immediate adverse reaction for Vanessa Trump, she was taken to an area hospital for observation and tests, the spokesman explained.
The white substance was undergoing tests to determine its identity, police said. Trump, 40, and his wife, the former Vanessa Haydon, were married in 2005 and have five children.
