Iowa Rep. Steve King reportedly plans to reintroduce a bill that would make English the official language of the U.S. The bill would require those trying to become naturalized U.S. citizens to be tested on their ability to read, write and speak English. It would also require that those pursuing U.S. citizenship be tested on their comprehension of the Declaration of Independence, the Constitution, and related texts. Lastly, it would mandate that official functions of the U.S. government be carried out in English, which could mean that voting ballots would appear in no language besides English.
