President Bush has accepted responsibility for his party's significant losses in Tuesday's mid-term elections, and he has acknowledged that they reflect voter frustration at the lack of progress in Iraq.
In a nationally televised news conference on Wednesday, Mr. Bush said he will work to find common ground with the incoming Democratic congressional leadership.
On the subject of Iraq, the president said the election results will not change his overall strategy for that war-torn country. He added that he will not order the withdrawal of U.S. forces from Iraq before the mission is complete.
Mr. Bush also announced the resignation of Secretary of Defense Donald Rumsfeld, saying the two had agreed the time is right for new leadership at the Pentagon.
The president said passage of comprehensive immigration reform, including his proposed guest worker program, is more likely now that Democrats control the House of Representatives. Republicans in the Congress have opposed some of Mr. Bush's proposals on immigration reform.
