The Senate and the House recently passed bills, by unanimous consent, without any public review (The Senate bill was S.716), to eviscerate the STOCK act of last year which required transparency in financial trading of legislators, legislative staff, and of the executive branch. President Obama signed this bill, ironically enough, on April 15, 2013 (Tax Day).
