The Senate Democrats and the Obama administration!
Oh the irony! For all the accusations about a war on women being waged by the Republicans it does appear the Senate Democrats and Obama administration just do not value their female staff members quite as much as their male counterparts.
Even more irony. Remember Senator Patty Murray? She's the one that has been ever so vocal about those evil Republicans and how unfairly they treat women...heh heh heh...she is the worst offender.
Senate Democrats pay female staffers less than male staffers
