WASHINGTON – President Barack Obama said Monday that an agreement to avoid the worst effects of the year-end fiscal cliff is "within sight," but he stressed that a deal is "not done yet," and House Republican leaders announced they would hold no votes Monday night, ensuring that the nation would go over the "fiscal cliff" for at least a day.

The announcement from the GOP-controlled House came after Obama urged lawmakers to "stop taxes going up for middle-class families, starting tomorrow," and he called on them to remain focused on the needs of the American people rather than politics.

In what the White House billed as an event with middle-class Americans, Obama said there were "still issues left to resolve" in the talks. He said he was "hopeful that Congress can get it done. But it's not done."
