I can't find any articles on the internet which describe Mr. Sam's views on anything at all. He's from the Umatilla reservation in eastern Oregon.
I did find a partial article that I can't link to that says that a memorial Mass and Rosary were held for Sam's father in 2019, at St. Andrew's mission church in Pendleton, Oregon; so Sam's father was likely Catholic (Novus Ordo), so maybe Charles F. Sams lll is at least baptized Catholic, in the new rite. Not sure that that means anything though.
