WASHINGTON (AP) — President Barack Obama is renewing his call for a comprehensive overhaul of the immigration system, telling Congress during his State of the Union address: "Now let's get this done."

He asked for a bill in the next few months and pledged to sign it "right away."

Obama wants legislation that would create a pathway to citizenship for the estimated 11 million illegal immigrants in the U.S., among other steps.

Eight Republican and Democratic senators are working to complete a bill by next month.

An aide says the four Democrats in the group — Chuck Schumer of New York, Dick Durbin of Illinois, Robert Menendez of New Jersey and Michael Bennet of Colorado — plan to update Obama on their progress during a meeting at the White House on Wednesday.
