Hazmat unit rushes to Don Jr.'s Florida home over letter containing white powder and death threat - as furious ex-president's son says 'this wouldn't be tolerated if I were a Democrat'

A letter containing white powder and a death threat was mailed to the Florida home of Donald Trump Jr. and Kimberly Guilfoyle, as hazmat crews and emergency services arrived to investigate Monday.

Trump Jr., 46, shared his outrage on the threats and said 'if this happened to a prominent Democrat it wouldn't be tolerated and would drive news coverage for weeks.'

Multiple first responders were on the scene at the $9.7million Jupiter home Trump Jr. co-owns with fiance Guilfoyle after he opened up the letter and reportedly white powder came flying out, The Daily Beast reported.

'The test results of the substance came up inconclusive on what it was exactly, but officials on the scene do not believe it is deadly,' a spokesperson for Trump Jr. said. 

However, that hasn't stopped the conservative firebrand from calling out a double standard in political media.

'It's just become a little bit too commonplace that this sort of stuff happens,' he told The Daily Caller. 

'Clearly, if this happened to a prominent Democrat it wouldn't be tolerated and would drive news coverage for weeks.' 

'The media would blame all Republicans and force them to answer for it, But since it's me, radical haters on the left will largely get a free pass and the media will barely flinch.'

He said that the incident was a sign of 'the left's hatred' of his father driving 'people to do such crazy things.

'It doesn't matter what your politics are, this type of crap is unacceptable,' he added. 

It's the second time white powder has been sent to the former president's oldest son. 

In 2018, his then-wife, Vanessa, was taken to a New York City hospital after she opened an envelope addressed to her husband that contained an unidentified white powder. 

Police later said the substance wasn´t dangerous.

Jupiter police said the investigation is being handled by the Palm Beach Sheriff's Office, which didn't immediately have any details to release.

Trump Jr. is one of his father's top campaign surrogates, frequently headlining events and appearing in interviews on his behalf.

In March 2016, police detectives and FBI agents investigated a threatening letter sent to the Manhattan apartment of Donald Trump Jr.´s brother Eric that also contained a white powder that turned out to be harmless.

Envelopes containing white powder were also sent twice in 2016 to Trump Tower, which served as Trump's campaign headquarters.

Hoax attacks using white powder play on fears that date to 2001, when letters containing deadly anthrax were mailed to news organizations and the offices of two U.S. senators. Those letters killed five people.
