After defeating incumbent Sen. Scott Brown of Massachusetts in a tight race, Democrat Elizabeth Warren thanked her supporters in Boston.
"We did what everyone thought was impossible," she said. "You taught a scrappy, first-time candidate how to get in the ring and win."
Warren, who painted herself as an advocate for the middle class, said her election is a sign that voters want someone in office to stand up to the "powerful Wall Street banks." She further drew big applause when she pointed to another result from her win.
"Despite the odds, you've elected the first woman senator to the state of Massachusetts," she said.
