Hillary Clinton reportedly paid the female staffers in her U.S. Senate office 28 percent less than men.
This revelation could complicate Clinton's ability to make income inequality a cornerstone of her potential presidential campaign in 2016.
As a U.S. Senator representing New York and after leaving office, Clinton championed closing the pay gap between men and women, as evidenced by the tweet embedded below, which appears to reference approximately the same differential that existed in her own office while she was an elected federal official.
Assuming the accuracy of the calculations, it turns out that Hillary Clinton apparently paid women 72 cents for every dollar earned by men under her employ from 2002 to 2008, the Washington Free Beacon reported.
"During those years, the median annual salary for a woman working in Clinton's office was $15,708.38 less than the median salary for a man, according to the analysis of data compiled from official Senate expenditure reports."
Pay discrimination on the basis of gender has been illegal under federal law since 1963.
Mrs. Clinton has also come under rhetorical fire for accepting millions of dollars in donations from foreign governments for the Clinton Foundation and also raking in about $81 million for the organization from seven individual donors via a Swiss bank allegedly used by one-percenters as a tax dodge. That she charges a six-figure fee for each speech made to a corporate or Wall Street group has also raised eyebrows across the ideological spectrum.
You may recall that in April 2014, the Obama administration's focus on the so-called gender pay gap during Equal Pay Day went sideways when it was revealed that women who work at the White House earn 88 cents on the dollar as compared to men, i.e., 12 percent less than their male counterparts.
