Obama to Delay Trip to Keep Up Pressure on Health Care Bill

House Democrats had told the White House that the schedule of the president’s trip to Asia and Australia was forcing them to rush the vote on the overhaul.

WASHINGTON — House and Senate Democratic leaders struggled Thursday to stitch together pieces of a final health care bill as rank-and-file Democrats demanded more information about the contents of the bill and its cost.

Leaving a meeting of the House Democratic Caucus, lawmakers said they had received few details about what would be in the legislation, on which they may be asked to vote in the next week or two.

“Everyone expressed frustration that we do not have comprehensive cost estimates from theCongressional Budget Office,” said Representative Gerald E. Connolly, Democrat of Virginia.
