A letter containing white powder and a threatening message was sent to the home of Donald Trump’s son on Thursday.
The envelope, which had a Massachusetts postmark, was addressed to Eric Trump, 32, at his apartment on the 14th floor of the Trump Parc East, according to The New York Post.
The letter reportedly contained a threatening message that implied that Donald Trump’s children would be hurt if the GOP candidate did not withdraw from the 2016 presidential race.
Eric's wife, Lara Yunaska, opened the envelope and white powder fell out, prompting police, fire crews and the FBI to respond.
It was not clear what the powder was, and an investigation in underway.
This comes after the hacker collective known as "Anonymous" claimed it hacked the Republican presidential front-runner's personal information and posted it online.
