House Majority Leader Eric Cantor’s (R-Va.) office said in a memo Wednesday that the chamber is expected to meet on Monday and “will not adjourn again until we have concluded our legislative business for the 1st Session of the 112th Congress.”

“While our goal is to complete all legislative business by Friday, December 16, Members are advised to keep their schedules flexible into the weekend of the 16th,” the memo reads. “Saturday and Sunday sessions are possible.”

The chamber was originally scheduled to adjourn on Thursday. As Cantor noted in a memo to lawmakers before the beginning of the current Congress, if the House had wrapped up busisness before that date, it would have marked the first time in 14 years that the chamber completed its work before its adjournment target.

The House is not expected to be in session this Friday; lawmakers are expected to wrap up their last votes of the week by 3 p.m. Thursday.

Dec. 16 is the deadline for Congress to pass a measure keeping the government funded. If it doesn’t, federal agencies may face a partial shutdown. In addition, lawmakers also have a Dec. 31 deadline for wrapping up other unfinished business such as extending a one-year payroll tax holiday and unemployment insurance and a provision to adjust the reimbursement rate for doctors who see Medicare patients.

Senate Democrats said earlier Wednesday that President Obama told them he will not leave Washington for his scheduled Hawaii vacation until Congress settles the payroll tax cut issue.
