The Washington, D.C.-based group Citizens for Responsibility and Ethics in Washington included Broun on its list of the "most corrupt members of Congress" released in September 2013. It was Broun's second consecutive year being included on the list. The group said, “ Broun "failed to disclose the true source and terms of loans he made to his campaign, illegally concealing the source of thousands of dollars in loans from 2007 to 2010." ” Broun is among thirteen members of Congress on the report. Four Democrats and nine Republicans are listed. Others included in the list are Senate Minority Leader Mitch McConnell and former presidential candidate Michele Bachmann.
Broun gave a speech at Liberty Baptist Church in Hartwell, Ga., on September 27, 2012, that included what some partisan critics characterized as "anti-science" comments. He referred to evolution, embryology and the Big Bang theory as "lies straight from the pit of hell." In response to the criticism, a spokeswoman for Broun explained the comments, and said that they were of a personal nature and that Broun was “speaking off the record to a large church group about his personal beliefs regarding religious issues.” At the time, Broun was a high-ranking member of the House Science Committee.
