The last undecided U.S. Senate race from Tuesday's election has gone to the Democrats, giving the opposition party control of both houses of Congress for the first time in 12 years.
The confirmation came when Republican George Allen conceded defeat Thursday in the Virginia senate race against Democrat Jim Webb.
Senator Harry Reid, who is set to become Senate Majority Leader when the new Congress convenes in January, told a rally in Washington that the election showed Americans want change. He called for a new direction in Iraq.
Congresswoman Nancy Pelosi, who is poised to become the first female Speaker of the House, met with President Bush Thursday. She said Democrats look forward to making progress on problems facing the country.
President Bush congratulated the Democrats, and called on both parties to set aside differences and work on important issues.
With the Virginia race settled, Democrats and Republicans will each have 49 of the Senate's 100 seats in the new Congress. However, two independents, Joe Lieberman of Connecticut and Bernie Sanders of Vermont have pledged to vote with the Democrats.
Democrats had already won a clear majority in the House of Representatives. The new session in January will be the first time in 12 years that the Democrats have controlled both houses of the legislature.
