Congressional leaders and rank-and-file lawmakers are expected to continue meeting on the $700 billion bailout package throughout the day, with Democratic leaders warning Members to be prepared for late-night votes, which may include a rule on the financial rescue bill.

A GOP aide said House Rules Chairwoman Louise Slaughter (D-N.Y.) told Republicans on the committee that the panel won’t meet for “hours and hours” but that the Democratic leadership is aiming for the committee to meet late Sunday to take up the sweeping economic rescue bill.

House Republicans are expected to huddle between 5 p.m. and 6 p.m. to review proposed changes to the package. After that, members of the conservative Republican Study Committee will meet to weigh in on the final bill.

The House is not expected to hold votes on remaining suspension bills until at least 4 p.m. House Majority Leader Steny Hoyer (D-Md.) sent out an advisory this afternoon indicating that the House will be in session “late tonight, with recorded votes expected.”
