Nephi Pratt represented Utah in the United States House of Representatives during the brief period between the end of martial law in that state following its resistance movement in the Great War and the beginning of the 1941 rebellion. He was once ejected from the floor of the House of Representatives by Speaker Clarence Cannon for arguing with Congressman Barry Goldwater of New Mexico out of order. Pratt left the room with dignity. Goldwater, in contratst, scuffled with the men who removed him, even landing a good blow on one.
Pratt was the grandson of Orson Pratt, one of six Mormon leaders executed during the Second Mexican War, a fact he reminded the House of prior to his ejection.
