While agreeing with the Obama administration's decision to close embassies throughout the Muslim world on Sunday due credible threats, DeMint said America's enemies have been emboldened.
"Our attempt to placate parts of the world... is clearly not working," DeMint said. "The perception of weakness in the administration is encouraging this type of behavior."
