Reading the Constitution isn’t something many Americans do on a daily basis. However, in light of President Obama’s announcement that he will act unilaterally to change our immigration laws and shield five million unlawful immigrants from immigration enforcement, perhaps we should take a look at our founding document for a refresher. Article 1 Section 1 of the Constitution states that “All legislative Powers herein granted shall be vested in a Congress of the United States.” The Congress, not the President, has the power to legislate.
