Congressman Ryan Audit the FED

HR459 titled the Federal Reserve Transparency Act of 2011 is currenty in committee in the U.S. House. Paul Ryan is the only Republican from WI not to consponsor it. Democrat Tammy Baldwin, U.S. Senate candidate has cosponsored it. What does Mr. Ryan have against transparency of the FED? Perhaps it has something to do with big business corporate interests as evidenced in his strong support of WI Gov. Scott Walker. There are currently 230 cosponsors which is enough to bring it to a full house vote scheduled in July. Congressman Ryan vote "YEA" for HR459
