Warren is part of an increasingly crowded and diverse field of Democrats vying for the chance to challenge President Donald Trump, the likely Republican nominee.
US Senator Elizabeth Warren, struggling to move past criticism over her claims of Native American heritage, aimed for a fresh start on Saturday with the formal launch of her 2020 presidential campaign, saying that she is fighting for all Americans.
The Massachusetts Democrat, a leader of the party's progressive wing, made her announcement from a historic site in Lawrence, northwest of Boston, that launched the US organized labour movement. Warren, 69, has made worker rights, fair wages and access to health care central to her campaign.
"This is the fight of our lives. The fight to build an America where dreams are possible, an America that works for everyone," Warren said. "And that is why I stand here today: to declare that I am a candidate for President of the United States of America."
Warren is part of an increasingly crowded and diverse field of Democrats vying for the chance to challenge President Donald Trump, the likely Republican nominee. A year before any ballots are cast in a Democratic primary, many of those candidates are spending this weekend talking to voters in the early nominating states of Iowa, New Hampshire and South Carolina.
Warren's announcement will be followed on Sunday by US Senator Amy Klobuchar, who has said she will reveal her presidential plans in her home state of Minnesota.
Warren's heritage claims have dogged her since her first campaign for the Senate in 2012, and Trump mockingly refers to her as "Pocahontas." Her ancestry drew fresh scrutiny earlier this week with the discovery that she described her race as American Indian on a form to join the Texas legal bar in the 1980s.
Warren has repeatedly apologized, saying the claim was based on "family lore" and she now understands tribal sovereignty dictates membership.
In addition to being a fierce Trump critic, Warren is an outspoken critic of Wall Street who gained national notoriety for her efforts to create the federal Consumer Financial Protection Bureau to regulate large banks.
Warren is one of four women so far seeking the Democratic nomination, an unprecedented number of female candidates vying to lead a country that has never had a woman chief executive.
Warren and the other women running so far, among whom are Senators Kamala Harris and Kirsten Gillibrand, are hoping to build on the success of women candidates who played a significant role in Democrats regaining control of the US House of Representatives in November's congressional elections.
