WASHINGTON — Congressional Democrats yesterday said President-elect Barack Obama probably will have to wait until next month before getting the chance to sign an economic aid bill his team once hoped would be on his desk by his swearing-in Jan. 20.

"It's going to be very difficult to get the package put together that early," House Majority Leader Steny Hoyer of Maryland said. "But we certainly want to see this package passed through the House of Representatives no later than the end of this month, get it over to the Senate, and have it to the president before we break" in mid-February.

Obama planned to meet with Senate Majority Leader Harry Reid, D-Nev., and House Speaker Nancy Pelosi, D-Calif., today to talk about enacting a massive spending plan. The president-elect also scheduled a separate meeting with the entire Democratic and Republican leadership teams.

Reid said they will do their "very very best" to get a package finished as soon as possible, but he was unwilling to set a deadline for completion.

Obama said Congress should pass a plan designed to create 3 million jobs. The Democratic president-elect hasn't announced a final price for the package, but aides said it could cost as much as $775 billion.

Congressional aides briefed on the measure say it probably would blend tax cuts of $500 to $1,000 for middle-class individuals and couples with about $200 billion to help revenue-starved states with their Medicaid programs and other operating costs. A large portion of the measure will go toward public works projects and include new programs such as research and development on energy efficiency and an expensive rebuilding of the information technology system for healthcare.

Senate Republican leader Mitch McConnell of Kentucky warned Democrats against trying to move quickly without the GOP's input.

"This is an enormous bill. It could be close to a $1 trillion spending bill," McConnell said. "Do we want to do it with essentially no hearings, no input, for example, in the Senate from Republican senators who represent half of the American population? I don't think that's a good idea."

Instead of giving all that money to states as grants, McConnell suggested it go as loans.

"It will make them spend it more wisely," McConnell said. "The states that didn't need it at all wouldn't take any."

Democrats understand that the GOP has to be involved in anything they do, said Sen. Dick Durbin of Illinois, the Senate's No. 2 Democrat.

"Mitch McConnell and Harry Reid both know that we can't pass the economic recovery plan that this nation desperately needs without bipartisan cooperation," Durbin said. "We've got to put aside a lot of the squabbling ... and come together under this new administration and new leadership, to get the American economy back on line."

Hoyer said they have only two criteria for passing an economic package.

"Do it as quickly as possible, but do it right, and do it so the American people know what we're doing, do it so that members of Congress are confident of the action that we're taking," Hoyer said. "So those are the two criteria — do it as quickly as possible, but do it right. I think that time frame is hopefully certainly by the end of the month."

Hoyer spoke on "Fox News Sunday," Reid appeared on NBC's "Meet the Press," while Durbin and McConnell were on "This Week" on ABC.
