The House will meet in the afternoon to take up a $1 trillion spending bill that's more than 1,500 pages long, and will pass it in a few short hours.

Members will consider the funding bill for the rest of 2014, which is being passed as a substitute amendment to an unrelated House bill, H.R. 3547.

On Tuesday, the House Rules Committee approved a rule for the bill that allows for just one hour of debate. That means members will debate the rule for an hour, then debate the bill for an hour, then pass the bill.

Democrats are expected to lament the GOP's decision not to allow any amendments to the bill, while some Republicans are likely to say they can't support the huge price tag of the measure. Still, it will pass and be sent to the Senate, which will have a few days to digest it and send it along to the White House.

The Senate will also consider 2014 spending on Wednesday, although it is one step behind the House. At noon, senators will debate a short-term spending bill that will keep the government funded through Saturday.

The House passed this short-term bill on Tuesday. It's needed to give the Senate time to move the bigger bill; once the Senate passes it, President Obama will have to sign it before midnight.

Senators will debate the short-term bill for 15 minutes before voting.

After that, senators are expected to continue working on an agreement allowing votes on a flood insurance bill. Senators from both parties have made several legislative proposals aimed at delaying scheduled increases in flood insurance premiums.

Under that bill, FEMA would also have to certify that it has accurately charted the correct levels of flood risk in areas that participate in the National Flood Insurance Program.

The Senate could also begin work on the $1 trillion omnibus spending bill late in the day, once it receives the bill from the House.
