Supreme Court Deadlocked on Obama's Immigration Plan

Today the U.S. Supreme Court deadlocked 4-4 on President Obama’s immigration plan, effectively blocking it. Two years ago, Obama took executive action to protect millions of undocumented immigrants from deportation. That was challenged in court by Texas and about two dozen other states. Today’s tie means that a lower court ruling siding with the states still stands. What does all this mean for some 5 million undocumented immigrants who would’ve been affected by Obama’s order?
