Scholten, a former baseball player, launched his run Monday with a video narrated by “Field of Dreams” star Kevin Costner.
Last fall, Scholten lost to King by only 3% of the vote, the closest margin for any of the Iowa congressman’s challengers during his nine terms in Congress.
After a long history of promoting racist and white nationalist rhetoric, as documented by HuffPost’s Chris Mathias last year, King has finally started to face some consequences. In January, after a New York Times interview in which he condoned white supremacy, GOP leaders removed him from congressional committees.
Scholten is the first Democrat so far to announce a run in the race against King, who represents Iowa’s fourth congressional district. Several Republicans have announced primary challenges against King.
