LAS VEGAS — Democratic presidential candidate Hillary Rodham Clinton said Tuesday that any immigration overhaul must include a path to “full and equal citizenship,” drawing a sharp contrast with Republicans who have promoted providing a legal status or blocked efforts in Congress to address the nation’s immigration system.

“This is where I differ with everybody on the Republican side. Make no mistake, today not a single Republican candidate, announced or potential, is clearly and consistently supporting a path to citizenship. Not one,” Clinton said, adding, “When they talk about legal status, that is code for second-class status.”

Clinton’s remarks during her first campaign stop in Nevada underscored Democrats’ efforts to box-in Republican presidential candidates who have opposed a comprehensive bill including a pathway to citizenship. Congressional Republicans have said the changes must be made incrementally, beginning with stronger border security.
