What is the religious denomination of the Koch brothers?

The Koch brothers are Catholic. Though their last name is Jewish in origin, the Koch brothers have pledged over $3 million to the Catholic University of America.

The wealthy Koch brothers are best known for making large donations to politicians, universities, and institutions that support their economically conservative views. The Koch brothers are self-proclaimed Libertarians, and believe in an unregulated free market economy. Many Catholics, including Pope Francis himself, have claimed that this type of extreme Capitalism is in contradiction to the teachings of the Catholic church. In light of this, many feel that the church should not accept the Koch brothers' large donations.
