Republican Sen. John McCain from Arizona, center, gets ready for a press conference in Mexico City, Friday, Feb. 22, 2013. McCain says he is guardedly optimistic about producing an immigration reform proposal that includes a path to legalization for illegal immigrants but significant disagreement remains between President Obama and a group of lawmakers drafting a bill.
