Warren announced her campaign in her home state of MA at a mill site where largely immigrant factory workers went on strike about 100 years ago, a fitting forum for the longtime consumer advocate to advance her platform. One of Donald Trump's favorite targets for verbal abuse, she's sure to draw quite a bit of attention in an increasingly crowded Democrat field.
The 69-year-old will then head to New Hampshire, home to the nation's first primary, where Warren could have an advantage as a neighboring-state resident with high name recognition. Warren's platform will focus on numerous same issues she's worked on since she was a Harvard Law School professor who helped President Barack Obama create the Consumer Financial Protection Bureau after the 2008 recession: cracking down on big banks, making corporations more accountable to workers, and expanding health care and housing for the middle class and low-income Americans. The Warren campaign eyed it as the place where families fought back against mill owners who sought to slash wages in 1912. California Representatives Ted Lieu, Katie Hill, and Nanette Barragán have all endorsed California Senator Kamala Harris, who officially announced her candidacy last month.
"It is time for her get out of the Senate, never mind running for the White House".
Her profile started to rise in the late 2000s for her commanding attitudes in favour of more rigorous regulations in response to the 2007-2008 financial crisis.
Despite their sparring history Ms Warren avoided taking direct jabs at President Trump - instead weaving specific policy prescriptions, such as the elimination of Washington "lobbying as we know it", into her remarks. After Republicans blocked her from running the Consumer Financial Protection Bureau, an agency she helped create, she ran for the Senate in 2012 and unseated a GOP incumbent. Democratic Mayor Dan Rivera praised Warren's selection of his city, which he said is dealing with numerous key issues Washington is trying to tackle, such as the opioid crisis and expanding affordable health care.
Ahead of the 2016 election, Democracy for America and MoveOn.org Political Action launched the "Run Warren Run" campaign to push the senator to enter the presidential race. Kirsten Gillibrand is visiting SC.
Immediately following her Lawrence announcement, the senator embarked on a seven-state organizing tour to drum up support for her campaign in New Hampshire, Iowa, South Carolina, Georgia, Nevada and California - must-win early primary states. Another possible presidential rival, Ohio Sen. Joe Kennedy III, D-Newtown; and Lori Trahan, D-Westford; U.S. Sen.
Saturday's announcement offered a new opportunity to make her case - and to change the subject.
She has been forced to apologise for claiming on several occasions in her early political career that she was of Native American descent.
Warren spoke at the site of the "Bread and Roses" strike of 1912, which pitted thousands of textile workers, majority women and many of them immigrants, against mill owners in a dispute over pay and working conditions that ended with the state becoming the first in the U.S.to pass a minimum wage law.
Another threat could come from a fellow senator who has yet to announce his own plans for 2020: Sanders. And as a senator from Vermont who won the New Hampshire primary, he would likely go into the Granite State as an early favorite if he chose to run again.
Speaking from Washington, Al Jazeera's correspondent Heidi Zhou-Castro said that as popular as Warren's wealth reform proposals may be with the liberal base, "she does have quite a liability with her claims of Native American ancestry".
