Billy Mawhiney, Executive Director of the South Dakota Afterschool Network appears to have filed paperwork last night to begin a run for Congress in 2026 as a Democrat, according to the Federal Elections Commission:

According to his bio, Mawhiney grew up on a farmland in a rural Missouri town of 113. He is a member of the Wyandotte Nation, and began his career in afterschool while in college at the Boys & Girls Clubs in Springfield, Missouri. Before South Dakota Afterschool Network, he was with the Boys & Girls Clubs of the Sioux Empire where he was the Director of Operations. He and his husband Kyle live in Sioux Falls.

That isn’t his bio.
You are correct. Not sure how that happened.
