The fiscally conservative Club for Growth may have opposed the compromise that raised the debt ceiling and led to the creation of the supercommittee of 12 members of Congress, but the organization has donated more to those members than any other.

The Club for Growth and its members have given just over $1 million to the campaigns of some of the committee's Republicans, including the group's former head, Sen. Pat Toomey (R-Pa.), as well as Sen. Jon Kyl (R-Ariz.) and Rep. Jeb Hensarling (R-Texas) according to a study by, a group which studies money in politics.

Most of the political action committees (PACs) on the list of donors were affiliated with private corporations, but on the liberal side, EMILY's List placed fifth on the list. The group and its members, who back Democratic women who support abortion rights, gave $595,000 to Sen.

Banks were also large donors to the members. Bank of America, Citigroup, JP Morgan Chase and Goldman Sachs all made the list of the top 10 organizations whose employees and PACs had given the most to the lawmakers.

“We’re proud of the impact our former President, Senator Pat Toomey is having on policy debates in Washington, and Club Members were proud to support Senator Kyl and Congressman Hensarling in their campaigns,” said Club for Growth spokesman Barney Keller. “The support of Club members and the impact Club for Growth PAC-endorsed candidates are having now reflect the fact that the Club for Growth is the most effective advocate of free-market principles in Washington.”
