SYRACUSE, N.Y. -- Ron Paul, the former presidential candidate and U.S. representative from Texas, delivered a speech about Libertarian principles tonight at Syracuse University's Hendricks Chapel.

Paul, a Republican who ran for president in 1988, 2008 and 2012, was invited to campus by SU's College Republicans club.

His son, U.S. Sen. Rand Paul, R-Kentucky, is considered a contender for the Republican nomination for president in 2016.

Earlier this week, Ron Paul answered questions from syracuse.com readers and reporter Michelle Breidenbach about his son, his views on U.S. involvement in Crimea, government spying and his popularity on college campuses.
