Elizabeth Warren announced on Saturday that she is launching an official bid for the presidency in 2020.
She was to be introduced by Rep. Joe Kennedy III, D-Mass., who meant to endorse her candidacy, according to an official familiar with his plans.
During her campaign launched, she spoke on Trump administration, saying "It won't be enough to just undo the bad acts of this administration".
She pointedly said of President Donald Trump, "The man in the White House is not the cause of what is broken".
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.
In her speech on Saturday in Lawrence, in her home state of Massachusetts, Ms Warren called Mr Trump "the latest and most extreme symptom of what's gone wrong in America, a product of a rigged system that props up the rich and powerful and kicks dirt on everyone else".
"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.
Warren has often spoken of how her parents eloped after her father's family disapproved of his future wife's Native American lineage, but Warren for years could never produce documentation to bolster her claims. In all, the race for the 2020 Democratic presidential nomination may be the most crowded field in US history.
"And she shouldn't presume that the scrutiny of her past is going to end as she formally launches her presidential campaign".
During her remarks, Warren repeatedly lambasted the fundamental injustice of a political system that rewards those with the deepest pockets at the expense of the most vulnerable. Bernie Sanders in 2016; Hillary Clinton, then a NY senator, in 2008; and then-Massachusetts Sen.
Warren reached out to Cherokee Nation leaders earlier this month to express regret over her decision to release DNA test results backing up her ancestry claims along with a video highlighting her "family story" in October. "I think the story needs to come back to more of that, which is hard in this day and age".
On Saturday, the President Trump's 2020 campaign called her a "fraud" minutes before she made her announcement.
Elizabeth Warren essentially has been disqualified from a presidential run by virtue of her claim, in 1986, to Native American race on her Texas bar registration card. A recent CNN poll found that fewer Democrats said they'd be very likely to support Warren if she runs than said the same of former Vice President Joe Biden or Sens. "I'm not taking applications from billionaires who want to run a super PAC on my behalf". "I was a Republican because I thought that those were the people who best supported markets", she said.
"All she's doing is trying to protect us when the story's twisted and, of course as usual, it's gets pushed on things like 'Oh, she said she's Native American.' Like, who cares about that?" she said.
Three of her fellow senators also are running - Kirsten Gillibrand of New York, Kamala Harris of California and Cory Booker of New Jersey - with others actively considering it. Minnesota Senator Amy Klobuchar is set to announce her plans on Sunday.
