ROUGH CUT (NO REPORTER NARRATION)<br/> <br />STORY: U.S. President Barack Obama on Monday said it appeared a deal on the "fiscal cliff" was within sight but it was not complete yet.<br/> <br />"Today it appears that an agreement to prevent this New Year's tax hike is within sight, but it is not done," Obama said at the White House.<br/> <br />U.S. Senate Republicans appeared to be coalescing around a potential solution to the crisis with a plan that would continue expiring tax cuts for household incomes of up to $450,000, congressional sources said.<br/> <br />"I think a majority of our caucus will go along with it," a senior Senate Republican aide told Reuters. Senate Democrats had not yet expressed positions on the emerging deal.
