The comments from Democratic Majority Leader Harry Reid and the Republican minority leader, Mitch McConnell, on the floor of the Senate prompted a delay in a meeting with US President Barack Obama and Vice President Joe Biden - another sign that hectic negotiations were under way.
The White House said that "important progress" was being made by the Senate leaders.
The postponement was greeted as a good sign by Republican Senator Susan Collins, who has led a bipartisan group in the Senate to forge a compromise that Reid and McConnell are apparently discussing.//DPA
