McCain guardedly optimistic on immigration reform

MEXICO CITY (AP) -- U.S. Sen. John McCain says he is guardedly optimistic about producing an immigration overhaul that includes a path to legalization for illegal immigrants, but he says significant disagreements remain between President Barack Obama and lawmakers.

Speaking in Mexico City on Friday, McCain told reporters that many details must be worked out between Obama and senators trying to produce legislation.

When asked if he thinks a deal can be reached, McCain said: "I am guardedly optimistic that we could by the end of the next month. There's still a number of agreements that need to be made before I can assure you that we will have a resolution."

McCain also said former Sen. Chuck Hagel was weakened by a confirmation battle but senators could work with him as defense secretary.
