Three days out from the deadline for Congress to raise the debt ceiling or else send the country into default, it remains to be seen whether leaders will be able to work out a bipartisan deal that can pass both chambers and be signed into law by President Obama before Tuesday.

Here’s what you can expect on Capitol Hill today:

The House is in at noon, with the first series of votes expected at 1 p.m. Instead of resuming work on an Interior appropriations bill, which the House had been considering this week, the chamber will vote on two post-office namings.

Then, at around 2 p.m., the House is expected to vote on the debt-ceiling plan put forward by Senate Majority Leader Harry Reid (D-Nev.). The vote will be on Reid’s original plan, not the reworked version he presented in the Senate on Friday night. Saturday’s House vote on the Reid bill will be taken under fast-track rules, meaning that a two-thirds majority is necessary for passage, no amendments can be made and debate will be limited to 40 minutes.

The House schedule is clear for the rest of the day.

The Senate, meanwhile, is in at 1 p.m. and will resume consideration of the Reid bill. From 1:30 p.m. to about 8 p.m., senators are expected to debate the measure.

Senators will take a vote on the Reid bill at 1 a.m. Sunday at the earliest – although that, like Senate business in general, is always subject to change.
