Minnesotans United for All Families is out with a web-ad campaign and petition to put pressure on the National Organization for Marriage to disclose its donors in Minnesota. NOM is notorious for shielding its donors through lawsuits and other legal action in at least a half-dozen states.

Here are the ads that have gone up this week:

MN United’s petition reads:

The National Organization for Marriage has launched an unprecedented effort in Minnesota to avoid disclosing individual donors as required by law.

Minnesotans United for All Families has openly reported contributions from over 5,000 individual donors. Sign the petition today and demand that NOM reveal their donors immediately.
