In a year of deadlines and political fights, Congress is closing with one last partisan brawl. At stake are billions of dollars in tax breaks and unemployment benefits for millions of Americans set to expire Jan. 1.

Just in case you've been out buying presents, working or not watching C-SPAN with bated breath, what happened Tuesday was that the House — specifically Republicans in the House — rejected a bill that had broad bipartisan support in the Senate.

One of the major sticking points between the House and the Senate as they face off over end-of-year legislation is the controversial Keystone XL pipeline. The bill the House passed Tuesday contains a provision forcing President Obama to decide on the pipeline within 60 days.

Republicans say this project should move ahead quickly because it will create thousands of jobs. But just how many jobs would be created is a matter of contention.

According to many polls, former House Speaker Newt Gingrich is now leading the Republican pack. His plan to rewrite the nation's tax policy hasn't gotten as much attention as some of his other proposals, but, according to a new analysis, it would require sweeping changes to the government.

Congress is supposed to head home for the holidays at the end of this week, but there's a whole lot of work to do before then. And for now at least, the parties remain divided over a number of other must-pass measures.

This is the part of the tango of Congress where the Republican House offers a plan.

"The House is going to do its job, and it's time for the Senate then to do its job," said House Speaker John Boehner, R-Ohio, at a press conference Monday.

Then, as if on cue, the Democratic Senate balked.

For the second week in a row, the Senate on Thursday voted down proposals to extend the payroll tax holiday through next year. In the case of the Democrats' proposal, Republicans objected to the "millionaires surtax" that would be used to pay for it.

Ever since the idea of the surtax was introduced weeks ago, Republicans in Congress have railed against it, arguing that it is a direct hit on small-business owners and other job creators.

Congress returned to Washington Monday with a pile of unfinished business, and no clarity on a path to getting it done. At the top of the congressional to-do list this week is extending a payroll tax holiday that meant about $1,000 in extra take-home pay for the typical family this year. It is set to expire at the end of the month.

Congressional leaders from both parties say the payroll tax cut is a must-pass measure. It's just not entirely clear how it's going to happen.

Herman Cain is a presidential candidate no more. Cain's campaign was always unconventional, and just as he made his unlikely rise to front-runner status, he was enveloped in controversy about alleged inappropriate behavior with women. His campaign never recovered. NPR's Tamara Keith looks back at his campaign.

Two different bills calling for an extension of a payroll tax holiday failed to pass the Senate late Thursday, but work on a compromise is continuing on Capitol Hill.

President Obama and Democratic lawmakers put forth concerted efforts to extend the measure, which is set to expire next month. Economists say failure to renew the tax cut, which allows the average American family to keep $900 a year of earnings, would hurt job growth.

The congressional to-do list for the month of December is long.

The list includes things like agreeing on a way to keep the federal government funded past the middle of the month, making some routine and annual tax fixes, and deciding whether or not to continue the payroll tax holiday and extended benefits for the long-term unemployed.

Dawn Deane, a 49-year-old human resources professional from Philadelphia is particularly interested in that last item.

Monday is the last day the congressional supercommittee can reach a deficit reduction deal and still make its Wednesday deadline. The legislation has to be publicly available for 48 hours before a vote and the clock is ticking, but instead of announcing an agreement, it is widely expected the committee will admit it has failed.
