Asked if the Senate would complete comprehensive legislation in the next two months, Sen. Harry Reid, D-Nev., said Tuesday: "We're not going to be bound by any timelines."
Reid said he was awaiting a final cost analysis on the bill from the Congressional Budget Office.
Obama has pressed Congress for a bill by year's end. Across the Capitol, the House is expected to vote on its version of legislation later this week. Lawmakers from both chambers then would have to meld the two bills and cast final votes in the House and Senate before the legislation could be sent to the president.
