Senator Elizabeth Warren is expected to formally launch her presidential bid in MA on Saturday with a populist call to fight economic inequality - a message she hopes will distinguish her in a crowded Democratic field and help her move past the controversy over her prior claims to Native American heritage.
Kennedy will announce his support for Warren in a speech introducing her Saturday, they said.
Warren introduced her campaign by telling the story of Lawrence, where laborers - many of whom were immigrants - toiled under bad working conditions.
Warren's announcement comes a little more than one month after she announced an exploratory committee, the first step major candidates take when considering a run for president.
Arguing that the struggles mill workers faced 100 years ago are similar to those million of American families face today, Warren said she - like the women of Lawrence - is here to say "enough is enough" and take her fight for USA middle class workers to the White House.
The senator laid out her campaign's vision of "big, structural change", which includes tackling wealth inequality, overhauling the criminal justice system, addressing climate change and rooting out corruption in Washington, among other things.
"This is the fight of our lives, the fight to build an America where dreams are possible and an America that works for everyone", she continued. "This go-around, Warren needs to deal with the issue now, rather than in October 2020".
How much effect the negative headlines will have on her in a crowded field will likely depend on how, or whether, Warren can put the controversy behind her.
"I am in that fight all the way", she told supporters. "Nevertheless, they persisted", she said about the strike, using one of her iconic campaign phrases to applause.
Ms Warren has always been a star in the progressive left, however, and she has already built a formidable nationwide campaign. "And that is why I stand here today: to declare that I am a candidate for President of the United States of America".
The disclosure prompted yet another public apology from the senator, just days after she had expressed remorse to Cherokee leaders for using a DNA test a year ago to try to show her Native American ancestry. The paper reported Tuesday that Warren listed her race as "American Indian" on her registration card for the State Bar of Texas dated April 1986. "I'm not taking applications from billionaires who want to run a super PAC on my behalf".
Trump refers to Warren as "Pocahontas", a slur referencing accusations that she falsely claimed Native American ancestry in a Harvard directory. She recently unveiled a proposal that pushes the frontier to a new place: directly taxing the very rich.
Unable to overcome Republican opposition to become the Director of the CFPB, Warren instead challenged and defeated Republican incumbent Senator Scott Brown of MA in 2012. Tribal activists, who were sharply critical over DNA test and earlier refusal to address the harm it might have done to their interests, have mostly welcomed her apologies.
