Obama became the first U.S. president to endorse allowing same sex-couples to marry legally.
"At a certain point I’ve just concluded that for me personally it is important for me to go ahead and affirm that I think same-sex couples should be able to get married," the president said in an interview with ABC's Robin Roberts.
"Of course in reality what really matters is what governors are saying," said Smith in his segment. "This makes no legal changes of any kind. This is a states' issue, at least for now, which may sound familiar to a couple of generations ago, but that's where we are."
After speaking with Fox News reporter Bret Baier about the ramifications of Obama's remarks, Smith also landed a jab at conservative critics of gay marriage. Smith asked whether Republicans would now campaign against gay marriage, "sitting very firmly, without much question, on the wrong side of history."
