Warren Launches Website, Exploratory Committee

WASHINGTON — Consumer advocate Elizabeth Warren is launching an exploratory committee and a website for a possible challenge against GOP Sen. Scott Brown, a top Democratic target in 2012.

Warren will use the committee and the Web site to begin raising money and lining up volunteers. A Massachusetts Democrat familiar with Warren's plans said the paperwork was filed Thursday for the exploratory committee. The Democrat requested anonymity because he was not authorized to speak publicly.

Warren is meeting with activists across the state and plans to decide after Labor Day whether she will run.
