The two-term chairman of the Minnesota College Republicans is the latest from his party to support legalizing gay marriage in the state.
Ryan Lyk tells The Associated Press he wants people to know that not just Democrats support gay marriage.
Lyk holds the top post of a group with 20 chapters statewide and several hundred members. He is the highest-ranking state GOP leader so far to break with the party's official stand against same-sex marriage.
The 21-year-old University of Minnesota student and former intern to Michele Bachmann says College Republicans are still split on the issue, but that an increasing number support gay marriage.
Minnesota's Legislature may vote on whether to legalize gay marriage later this spring. So far only one Republican lawmaker openly supports the bill.
