WASHINGTON (AP) - White House chief of staff Denis McDonough says President Barack Obama is working with a bipartisan group of senators on an immigration overhaul and hasn't made any proposals yet.

USA Today is reporting the White House has drafted a plan that would create a visa for those in the country illegally and allow them to become legal permanent residents within eight years.

GOP Sen. Marco Rubio of Florida says if such a measure was proposed, it would be "dead on arrival" in Congress.

But McDonough says that the White House would only go forward with a plan if lawmakers fail in their efforts, adding "let's make sure that it doesn't have to be proposed."
