The U.S. Senate postponed a series of votes scheduled for Monday evening due to inclement weather in Washington.

Majority Leader Harry M. Reid (D-Nev.) announced Monday afternoon that votes scheduled for this evening will be postponed until Tuesday morning. Reid said Senate leaders had been scrambling most of the day to determine whether enough senators would return in time for the votes.

The delay means that a vote to confirm Patricia A. Millett to serve on the U.S. Court of Appeals for the District of Columbia will have to wait until at least Tuesday. Millett is slated to be the first of three picks by President Obama to serve on the powerful court that Senate Democrats would like to approve by the end of the year.

In addition to the icy weather, at least two senators were not scheduled to be in Washington Monday: Sen. Ted Cruz (R-Tex.) is part of the congressional delegation traveling to South Africa to attend a memorial service for Nelson Mandela, while Sen. Mark Kirk (R-Ill.) is recovering from surgery to remove his gall bladder.

While notable, the postponement is nothing new: This is at least the third time this year that the Senate has postponed Monday evening votes due to bad weather or the lack of a quorum.
