Kentucky Senator Rand Paul, a possible 2016 presidential candidate, this week signaled he could be evolving on the issue of marriage equality.

Speaking to CNN's Peter Hamby, Paul reiterated his opposition to marriage equality, but not before stating that “even within the Republican Party” people are rethinking the issue.

“Society's changing,” Paul said.

“I mean, people change their minds all the time on this issue, and even within the Republican Party, there are people whose child turns out to be gay and they're like, 'Oh well maybe I want to rethink this issue.' So it's been rethought. The president's rethought the issue. So I mean, a lot of people have rethought the issue.”

“The bottom line is, I'm old fashioned, I'm a traditionalist. But I don't really think the government needs to be too involved with this, and I think that the Republican Party can have people on both sides of the issue.”

When Hamby asked, “You could rethink it at some point, too?” Paul just shrugged.
