Republican Sen. Jeff Flake says it is "inevitable" that his party will see one of its own run for president while supporting gay marriage.
The Arizona lawmaker on Sunday said the shifting political landscape will eventually yield a candidate who backs same-sex marriage and predicts that candidate would find support within the GOP.
Fellow Republican Senators Rob Portman of Ohio has announced his support for gay marriage in states that choose to allow such unions and Lisa Murkowski of Alaska says her position is "evolving." Scores of Democrats in recent weeks have announced their support for gay marriages.
Flake says he still believes marriage should be restricted to straight couples and said he doesn't imagine he would change his position.
Flake spoke to NBC's "Meet the Press."
