Fred Karger, a gay Republican whose 2012 presidential-nomination campaign garnered little national attention, has filed a complaint with the Federal Election Commission against fellow 2012 Republican presidential-nomination candidate Rick Santorum.

Karger’s complaint in a Wednesday press release alleges the Washington D.C.-based National Organization for Marriage, Santorum, and Bob Vander Plaats conspired in garnering Vander Plaats’ Santorum endorsement two weeks prior to the 2012 Iowa caucuses in return for money.

Karger founded Rights Equal Rights, formerly known as Californians Against Hate, in 2008 in attempts to draw attention to major campaign donors to vote yes on Proposition 8, a 2008 California ballot issue established to define marriage as existing only between a man and a woman, according to the organization’s website.
