But Santorum said he did not support a state in which English was not the primary language. “Like any other state, there has to be compliance with this and any other federal law,” Santorum said. “And that is that English has to be the principal language.

But as Reuters goes on to point out, “the U.S. Constitution does not designate an official language” and there is no extant legal “requirement that a territory adopt English as its primary language in order to become a state,” so it’s hard to say what “compliance” issue exists, other than Rick Santorum just really, really wanting them to speak English.
