Anderson Cooper spoke with Senator John McCain about the ongoing humanitarian crisis in Syria two years after civilian protests began, leading to a brutal crackdown by President Bashar al-Assad and a violent conflict between government forces and the opposition.
They also discussed the issue of same-sex marriage in light of Republican Senator Rob Portman's announcement that he now supports gay marriage because his 21-year-old son is gay. McCain says he respect's Portman's decision, but disagrees because of his religious beliefs.
