This recipe is from my mom's recipe box. It has to be about 1963 or 1964. The senator, Daniel B. Brewster, is named as the person whose kindness helped "us housewives cook Capitol Hill's famous Bean Soup" served in the senate from 1963 to 1969. Mom died in 1964 so that narrows the date.
What a simple recipe. Wonder if the House still has it on their menu?
