WASHINGTON (AP) — The Senate has been in session all night.

Republicans are fuming over Democrats' new limits on filibusters and refusing to give up debate time over 11 presidential nominations that Majority Leader Harry Reid is trying to push through this week.

Reid is threatening to keep the Senate in continuous session through Saturday, unless Republicans relent. So far, there no sign of that happening.

Early Thursday, the Senate confirmed the first of those nominees, voting 51-44 to confirm Cornelia "Nina" Pillard to the influential D.C. Circuit Court.

The Senate also is slated to consider Jeh Johnson, Obama's pick to head the Homeland Security Department. The nominations don't appear to be in jeopardy despite the infighting.
