White House press secretary Robert Gibbs said Monday that President Obama will postpone his Hawaii Christmas vacation until Congress adjourns for the year.

The outgoing Democratic Congress still has much work to do before adjourning on a number of issues key to the administration.

Obama previously said he would stay in Washington until the Senate voted to ratify the START nuclear arms treaty, but Gibbs said Monday that as long as Congress is in Washington, Obama will be in the White House.

Gibbs said Obama wants to see Congress approve his tax deal, ratify START and hopefully make progress on passing the DREAM Act and repealing the military's "Don't ask, don't tell" ban on gays serving openly.

Gibbs all but declared that because of the schedule, Obama's planned departure this weekend will be pushed back.
