Cruz’s new ad is an example of a false talking point that has been honed to the point of ridiculousness....In the ad, Cruz attempts to knock one of his main rivals for the GOP presidential nomination, Sen. Marco Rubio (Fla.), for his efforts in 2013 to foster a compromise on an immigration overhaul — while also playing on fears about the rise of the Islamic State militant group, which has captured significant territory in Iraq and Syria and is also known as ISIS....Cruz has truncated his argument in the ad: “Their misguided plan would have given President Obama the authority to admit Syrian refugees, including ISIS terrorists. That’s just wrong.”

Actually, this statement is simply bizarre. With or without the Senate immigration bill, Obama had the authority to admit refugees, from any country, under the Refugee Act of 1980, as long as they are refugees and are admissible. Every president since the passage of the law — Ronald Reagan, George H.W. Bush, Bill Clinton, George W. Bush and Obama — has exercised that right repeatedly for hundreds of thousands of refugees.

What does ISIS have to do with it? Nothing. Terrorists are not admissible under the laws of the United States.
