Yesterday Dan Patrick, the Republican nominee for lieutenant-governor, released a new television ad arguing that the pragmatic approach to illegal immigration favored by his Democractic opponent, Leticia Van de Putte, has left Americans vulnerable "while ISIS terrorists threaten to cross our border and kill Americans."
He's referring, implicitly, to the United States's southern border with Mexico, and Patrick is not the only Republican to be raising this specter. Last month Jason Chaffetz, a Republican from Utah, said that he "had reason to believe" that four terror suspects--not affiliated with ISIS, but affiliated with other terrorist organizations--had been apprehended in Texas on September 10th. Several days ago Duncan Hunter, a Republican representative from California, told Fox News host Greta van Susteren that "at least ten ISIS fighters have been caught coming across the border in Texas."
There are many substantive disagreements between Patrick and Van de Putte about illegal immigration and border security, and Patrick has been calling for a greater focus on border security for years, but since he dragged ISIS into it, let's talk about that. Hypothetically speaking, an ISiS fighter could try to enter the United States by sneaking across the border into Texas, but the "evidence" cited in all three cases doesn't stand up. In reality there is no evidence that any ISIS fighters have illegally entered Texas, and no evidence that any are even making a serious attempt to do so.
