WASHINGTON -- Sen. Marco Rubio (R-Fla.) attacked President Barack Obama's new immigration policy on Sunday, claiming that the new standard, which grants certain young undocumented immigrants a reprieve from deportation, "injects politics" into the debate over immigration."It's a short-term fix for a long-term problem," Rubio said on "NBC's Meet The Press." "The issue has been politicized by the president."Immigration has been a deeply political issue for years.
