In an interview on Morning Joe today, Rand Paul claimed Republicans created ISIS:
ISIS exists and grew stronger because of the hawks in our party who gave arms indiscriminately. And most of those arms were snatched up by ISIS. These hawks also wanted to bomb [Syrian President Bashar al-Assad], which would have made ISIS's job even easier. They created these people. ISIS is all over Libya because these same hawks in my party loved -- they loved Hillary Clinton’s war in Libya. They just wanted more of it.
That's not the way I remember things. As I remember it, Republicans wanted Congress to have a say over American military involvement in Libya given that the Arab League, NATO and the UN vetted the thing.
