The mother of a Wisconsin congressional candidate Randy Bryce doesn't like to see her sons fight.
Nancy Bryce, in an open letter Wednesday, called for an attack ad featuring Randy's brother James to be taken off the air.
"My family deserves better than this," she wrote. "All families deserve better than this."
Randy Bryce, known by the colorful nickname "Iron Stache," is a Democrat running to replace House Speaker Paul Ryan, who is leaving Congress. Bryan Steil, a former Ryan aide, is the Republican running in the southeastern Wisconsin district.
