Rick Santorum's contention that in order for Puerto Rico to become a state English must be its principal language drew criticism Thursday from the U.S. territory's sole representative in Congress.

"Santorum's view is narrow and a limiting view of what America is all about," said Pedro Pierluisi, a Democrat, on CNN's "Starting Point." "English is the predominant language in the U.S. and will continue to be so, whether Puerto Rico becomes a state or not."

Puerto Rico will vote in November on a referendum regarding possible statehood.
