Late Sunday night, the two parties had slightly different reactions to the news. Democrats largely thanked Obama for his efforts to kill bin Laden, with some, like Rep. Gary Ackerman (D-N.Y.), saying that this is the "mission accomplished" moment that Bush "only fantasized about."

In contrast, Republicans thanked both Obama and Bush for their efforts over the last nine and a half years to track down and finally kill bin Laden, and are expected to continue on that track today.

The House returns at 2 p.m. to take up the Bush-courthouse bill, H.R. 362, and another bill naming a post office in Oklahoma. Votes on these bills are expected by 6:30 p.m.

Also returning at 2 p.m. is the Senate, where members are also likely to take much of the day to speak about the death of bin Laden.
