Republicans are butting heads over President Barack Obama's decision to ease restrictions on Cuba. Sen. Rand Paul (R-Ky.) came out in support of the policy move, declaring that "the 50-year embargo just hasn't worked."
Sen. Marco Rubio (R-Fla.) didn't spare his colleague, firing shots back on TV.
"Like so many people who have been opining, he has no idea what he's talking about," Rubio told Fox News. "The embargo is not what's hurting the Cuban people, it's the lack of freedom and the lack of competent leaders."
