An Iowa man accused of making threatening and anti-Semitic calls to a New York City Jewish organization was released on a $50,000 bond following a short hearing in Manhattan federal court Wednesday.

Garrett Kelsey kept his mouth shut when asked to comment on allegations that he’d contacted an unspecified local Jewish organization in May, allegedly saying, “My people have f—ing slaughtered your f—ing people before and we will do it again.”

The vitriol was apparently a response to the unspecified organization posting a video about “Nordic Neo-Nazis” to their website, according to court papers.

“Everywhere the Jews go in the world they cause trouble. You have 3 days to remove this video and offer an apology to the Asatru community or we will be taking action against your organization full of degenerates,” read the email, which he allegedly sent under the name Garrett Odinschild. The court papers describe Asatru as “a neo-religious movement aimed at reviving Norse beliefs.”

The 31-year-old is charged with one count of transmitting threats to injure a person across state lines, and faces up to five years behind bars if convicted.

Under the terms of his release, Kelsey is subject to electronic monitoring and home detention in Iowa. He may only travel to the Northern District of Iowa and New York’s Eastern and Southern districts for court appearances. Kelley is also not allowed to contact the organization in any way.

He has not entered a plea. His attorneys declined to comment outside of court.
