SEATTLE — Organizers of Referendum 71 to repeal Washington state’s gay partnership law want the names of their donors to remain secret.

Protect Marriage Washington asked the Public Disclosure Commission on Thursday to hold an emergency hearing. According to the group’s letter, the R-71 campaign has received threats of violence against churches, property and supporters of the campaign.

In a news release the group says a threat of violence posted on the Web site Queer Equality Revolution was forwarded to the FBI.

Protect Marriage Washington is trying to repeal the so-called “everything but marriage” law, which would expand gay partnership rights. A federal judge has granted a temporary restraining order to bar the release of signatures on R-71 petitions, which are still being counted.
