NEW YORK (CBS) — The wife of Donald Trump Jr. was taken to the hospital for evaluation after opening a letter containing white powder inside.

CBS New York reports the letter was addressed to Trump Jr. and was sent to the Sutton Place home he shares with his wife, Vanessa Trump.

According to CBS New York, Vanessa Trump opened the envelope and discovered the white powder.

Police say she then called 911, complaining of nausea and a cough.

President Donald Trump’s daughter-in-law and two others were taken to the hospital for evaluation.

Law enforcement sources tell CBS New York that preliminary tests show the white powder was not harmful.

It is not yet known what the substance is.

A woman who lives in the building called the incident “terrifying.”

“I think it’s terrifying. I think it’s terrifying anyone would send a package like that, regardless of who it’s to. It’s terrible,” said Lois Winston.

According to White House Press Secretary Sarah Sanders, the president spoke to his daughter-in-law Monday afternoon.

On Twitter, Trump Jr. said, “Thankful that Vanessa & my children are safe and unharmed after the incredibly scary situation that occurred this morning. Truly disgusting that certain individuals choose to express their opposing views with such disturbing behavior.”

 

The NYPD and Secret Service are investigating the incident.
