Elizabeth Warren will announce tomorrow that she is officially running for the U.S. Senate, a Warren adviser tells NBC News.
She will start out in Boston meeting with commuters, then make three more stops.
“The pressures on middle-class families are worse than ever, but it is the big corporations that get their way in Washington,” Warren said in a statement. “I want to change that. I will work my heart out to earn the trust of the people of Massachusetts.”
Warren -- who served as the chairwoman of the Congressional Oversight Panel, created after the 2008 financial collapse -- faces a crowded primary and a potentially tough fight against a popular incumbent Republican in Scott Brown. Democrats hope to make this a competitive race in a presidential year in a blue state.
