Denver, Colorado (CNN) - In an interview with CNN, Colorado's Republican Senatorial nominee Ken Buck made clear he believes in the separation of church and state. He defended comments he made last year during a candidates forum in which he challenged the way courts have interpreted the First Amendment's religious protections.
Buck told CNN, "I have said I agree with the establishment clause. I agree with the idea that there is a separation of church and state. That teachers should not be leading prayer – a particular kind of prayer in classrooms. What I have said is that I think the federal government and we as a society have come too far in trying to separate good organizations that perform good functions for people just based on the fact one has a religious association and one doesn't."
