US Gov should clean up its own act first
According to breitbart.com (YMMV) Senator Elizabeth Warren's office pays women $0.71 cents on the dollar vs. men. Former Senator Hillary Clinton paid women $15k less per year than men. Former Secretary of State Hillary Clinton paid women $16k less per year than men. For presidential candidate Hillary Clinton paid women $7k less per year than men. I am sure their are plenty of examples on both side of the isle, but I am lazy so just using the one source.
I think this is more about someone in DoL trying to make a name for themselves, or possibly an excuse to build a who's-who list of Google employees using personal information.
