Wish we could find out who is funding that prick. Last I heard it is is just him and his kids. There is no 'church' beyond them.
Westboro has 70 members. I would imagine that they could be funded by the same group that funds the ACLU. Even $250,000 would not be enough to do their 40 protests a week. WBC is made up of the Phelpses, Hockenbargers, Chris Davis (married to one of the Phelpses), Teresa Davis (relationship to Chris Davis is unknown), George Stutzman (rumored to have an affair with Margie Phelps), and the Drains, who were newly converts and joined in 2000. There is a de facto member who keeps in contact with WBC and pickets with them named Bart McQueary. He was a wrestler promoter, pornographer, and statutory rapist/fornificator and he was accepted by WBC, despite the fact they are anti-adultery/anti-fornification. Another person I suspect is likely colluding with WBC is Michael Crook because he shares the same sentiments with Fred Phelps, especially they share the same hatred for gays, soldiers, young people who die, and Christians. Crook also praised WBC and Phelpses and called them "heroic". However, Crook is pro-adultery, pro-abortion, divorced twice, and is possibly bisexual/gay. Than again as pointed out, they accepted McQueary, despite the fact he is a pornographer and fornificator.
