Suspicious material in letters to Straight Pride Parade organizers turned out to be... glitter!

Organizers of the planned "Straight Pride Parade" in Boston next month called police after receiving suspicious envelopes containing a powdery substance. A hazmat team investigated and the mystery material turned out to be... glitter. From The Guardian:

The suspicious envelopes, filled with a "granular substance", were addressed to three members of "Super Happy Fun America", a group whose membership have previously organized and attended events, some of which have turned violent and who have links to far-right figures.

One of the recipients, Mark Sahady, is known as the leader of the Boston chapter of a group called Resist Marxism, an organization described by the Daily Beast as the new organization as a "front for [the] far-right group".

In 2018, Think Progress reported that Resist Marxism had links with white nationalist groups, and that members had expressed antisemitic sentiments in leaked chats.

The sender or senders of the glitter parcels remains unknown.
