At a recent White House ceremony to naturalize 24 members of the U.S. military, President Barack Obama called on Congress to overhaul the nation's broken immigration system. In his remarks, the president praised U.S. Sen. Charles Schumer, D-N.Y., for working to forge bipartisan support for comprehensive immigration reform… Schumer's assertion that the worker ID cards will be used only for employment purposes ignores history. For decades, Social Security cards were stamped with an admonishment that they were not for identity purposes. Over the years, the cards have become essential identity documents. The same undoubtedly would happen with a biometric worker ID card. They would soon be required for any number of activities, including voting, obtaining government benefits, buying a gun, etc.
