Hi,
Just wanted to wish you luck in your battle in Cedar City and share what I've learned about NAGA. I have no information that isn't available through web searches, searches of non-profit sites, etc, but did spend a certain amount of time going through thousands of web pages trying to figure out who was behind them and who funds them.
They were brought in by the faction in Anderson Township, Ohio that was lobbying to keep the "Redskin" nickname for Anderson High School. They were mainly represented in Anderson by Eunice Davidson and Tony Henson. In general, they volunteer to join all such fights around the country and provide cover for the local groups, who can then claim "See, there are lots of Native Americans who support us!" I don't know what the process is in Cedar City, but in Anderson there was no forum to challenge their status, funding, or credentials. The committee running the process simply allowed any interested party to make 3 minute statements at open meetings, and that is where NAGA weighed in. They also provided so-called "research materials" to the local group they were supporting, which consisted of the Washington Post poll, articles written by Billeaudeaux, etc.
Billeaudeaux's entire pre-NAGA career was in the Coast Guard. He joined right out of high school and had the usual low-level jobs on cutters. They sent him to get a bachelor's, master's, officer candidate school, and post-graduate training. Most of his professional career was as an in-house reporter and public relations guy. He keeps his online profile very buttoned-down...his LinkedIn account is basically an unused stub, as is his Twitter account. You can glean very little from his public Facebook postings other than the fact he is a big Trump MAGA supporter and a Build the Wall guy. He has made some claims about himself that are kinda sorta true but don't really stand up to scrutiny. For example, he claims to be a commentator for CNS News, a right wing site run by Brent Bozell. He wrote some articles for them in 2015 at the height of the controversy over the Washington Redskins name and has published nothing there since then. He also claims to be associated with a "federal think tank" in Monterey, CA. To the best of my knowledge, there are no federally funded think tanks in Monterey, which might explain why he never lists the name. He has also claimed to be "an award winning student of Philip Zimbardo". He never studied under Zimbardo. The truth is that one of his post-graduate schools gave him an award that they called in-house the Zimbardo Award. He also claims to be a "defense strategic analyst", but there is no record of this other than being a media flack for the USCG.
He retired from the coast guard in 2012 and had no visible employment until starting NAGA in 2014. His first foray into the Native American nickname controversy was writing a children's book called "How the Redskins Got Their Name" in 2015. It has zero reviews on Amazon, and there have been a couple of scholarly articles debunking his thesis.
Despite forming in 2014, NAGA did not register as a non-profit 501 (c) 3 until 2017. They have never disclosed who provided the seed money or subsequent funding. They have never filed the required non-profit financial disclosure forms since registering, claiming an exemption of being under $50,000. This seems ludicrous to me, as they have sent dozens of representatives around the country to various nickname battles, and I doubt that Billeaudeaux has been working for free since 2014. Until very recently, they did not have a website or any on-line mechanism to even donate, so they certainly weren't living on small donations. One of the Anderson Township "keepers", Veldkamp, is the one who put up a website for them within the past few months.
My best guess is that the impetus to create the organization came from Dan Snyder, owner of the Washington Redskins at the time there was a big push to change the name, and I suspect he is also the source of their seed money. Can't prove it, but the timing and motivation make sense because that was the first battle Billeaudeaux entered into.
That's about all I know. I would be happy to put you in touch with some of the folks who led the battle to change the name in Anderson (we lost, by the way). They would probably know more about some of the other NAGA folks who showed up and spoke.
Hope this helps you.
