From Wikipedia:
At an Atlas Society meeting celebrating Ayn Rand's life in 2005, Ryan said that "The reason I got involved in public service, by and large, if I had to credit one thinker, one person, it would be Ayn Rand", and "I grew up reading Ayn Rand and it taught me quite a bit about who I am and what my value systems are, and what my beliefs are. It’s inspired me so much that it’s required reading in my office for all my interns and my staff."
