The rally for Warren's announcement took place in Lawrence, Massachusetts, the site of a 1912 strike by textile workers, making it a symbolic location to launch a campaign largely focused on economic inequality.
There were some in Ms Warren's campaign kick-off crowd who expressed concern that her struggles to explain her past claims of Native American heritage could make her vulnerable to attack.
Trump campaign manager Brad Parscale said in a statement Saturday that Warren has been "exposed as a fraud by the Native Americans she impersonated and disrespected to advance her professional career, and the people of MA she deceived to get elected".
"Now when I talk about this, some rich guys scream, 'class warfare!' Well let me tell you something: These same rich guys have been waging class warfare against hardworking people for decades", the senator added. Since being elected to the Senate in 2012, Warren has stood on the most progressive end of the Democratic Party, advocating higher taxes on the wealthy and consumer protections.
Warren's nascent campaign has been plagued with controversy over a DNA test she took in the fall to show that she has some Native American heritage. 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.
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.
For her 2020 campaign, Warren has proposed a 2% wealth tax on fortunes of $50m or greater and a 3% tax on fortunes $1bn or greater.
She used the backdrop to highlight what she sees as the plight of an American working class that has been left behind by rapacious big business and indifferent government. "This go-around, Warren needs to deal with the issue now, rather than in October 2020". "I say it's time to fight back".
But even as Warren sharpens her policy positions and political message, the specter of additional, previously undisclosed examples of Warren labeling herself Native American on professional forms looms in the background. In 2012, her run for the U.S. Senate in MA was overshadowed by reporting that she was listed for years as a minority in the Association of American Law Schools directory and as Native American while teaching law at Harvard and the University of Pennsylvania. "I'm not taking applications from billionaires who want to run a super PAC on my behalf".
Joan Vennochi ("Warren can't beat Trump") is assisting the GOP in its effort to tear down Elizabeth Warren, whom the Republicans probably know may be the most formidable opponent to President Trump in 2020.
Ms Warren intends to spend Sunday in Iowa, where the lead-off caucuses will be the first test of candidates' viability. Kamala Harris (D-Calif.) announced her campaign last month, while Sen.
