WASHINGTON (AP) — It's a goal that will be hard to meet, given the resistance of many House Republicans -- but President Barack Obama is calling on Congress to finish work on an immigration overhaul by the end of the year.

The issue remains one of Obama's top second-term priorities, but it's been overshadowed for months -- most recently by the government shutdown.

The Senate has passed a measure that would provide an eventual path to citizenship for those who are in the country illegally, and would tighten border security. But it's gone nowhere in the Republican-controlled House.

During an event in the East Room, Obama said, "It doesn't get easier to pull it off."
