A Washington state man has been arrested by the FBI after he allegedly threatened to “personally execute” Jared Kushner, Donald Trump’s senior advisor and son-in-law.

Chase Bliss Colasurdo also made threats on social media platforms that he would kill Donald Trump Jr. and bomb Jewish places of worship, court documents alleged.

Colasurdo reportedly has a history of mental illness and has two previous arrests for assault.

He allegedly sent emails to five media outlets saying “I’m going to personally execute [Kushner] for his countless treasonous crimes.” This was followed by an image posted to his Instagram feed of Colasurdo aiming a gun at a picture of Mr Kushner.

After a search warrant was executed, Colasurdo was found to have stockpiled 345 rounds of ammunition, holsters, and a few items of Nazi memorabilia, including a framed picture of Adolf Hitler and a flag with a swastika on it in his home.

He had previously attempted to obtain a firearm, but was denied due to a Secret Service alert.

The FBI also claims that Colasurdo said: “This sneaky mossad agent has never been so serious about something as he is about putting a bullet in [Kushner’s] brain. It must be done,” referring to conspiracy theories surrounding the Mossad, an Israeli intelligence force.
