U.S. Senator Elizabeth Warren, a progressive Democrat who has often railed against what she sees as unfair treatment of women, joined the ranks of the scolded. According to an analysis of publicly available Senate data, the gender pay gap in Sen. Warren’s office is even wider than the national average. In 2016, the analysis showed, women working for Sen. Warren were paid just $.71 for every dollar paid to men.”
