Vice President Biden is expected to pay a visit to Capitol Hill tonight to talk to congressional Democrats about the outlines of a deal, according to multiple reports.

Fox News Channel's Ed Henry reports that the visit is likely to be an effort by the White House to "calm anxious Dems who think too much given away on taxes."

In a sign that Senate leaders may be anticipating a vote on a deal later tonight or in the wee hours on Tuesday, Democrats announced that the chamber will continue meeting until at least 9 p.m.

Meanwhile, the House has adjourned for the evening and, as expected, will reconvene at noon on Tuesday.
