Elizabeth Warren (D-Mass.) officially launched her 2020 presidential campaign in Lawrence, Massachusetts on Saturday with a call for bold reforms to America's dysfunctional economic and political status quo.

Another unanswered question: whether the dust-ups will permanently undermine Warren's campaign.

"Today, today, we come together ready to raise our voices together until this fight is won ..."

The announcement came after a hard week for Warren.

"America's middle class is under attack", Warren said in the announcement video in December.

When probed by reporters about more documents this week, she alluded to the possibility that there were more in existence on which she claimed she is Native American.

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.

Warren introduced her campaign by telling the story of Lawrence, where laborers - many of whom were immigrants - toiled under bad working conditions. With Everett Mill as the backdrop, where women and immigrant cotton weavers in 1912 went on strike for higher pay, she used the story of combating big business and fighting for workers' rights to announce her candidacy a little more than a month after forming her 2020 exploratory committee. "This is the fight of our lives", she said, according to CNN. "And that is why I stand here today to declare that I am a candidate for president of the United States of America", she said.

But even some of those who attended the kickoff had concerns about the strength of her candidacy, given the identity issue and President Trump's aggressive campaign style. "Warren has left herself open on a couple fronts to pile on". She's long advocated for more aggressive action to combat climate change and for higher taxes for the nation's wealthiest.

Others anxious that the country isn't ready for a female president.

Callahan, who noted that he's looking at other progressive candidates, said he'd like to see White House hopefuls make gun control, student loans, income inequality and LGBTQ issues top priorities in 2020.

President Donald Trump frequently derided Warren as "Pocahontas" beginning in 2016 when she would blast the then-Republican nominee, and she eventually released a DNA test showing she had a distant Native American ancestor to try to quell the controversy. The Green New Deal, supported by an array of Democrats, is a sweeping environmental initiative.

After her speech in Lawrence, Warren will head that same afternoon to an organizing event in Dover, New Hampshire. "There will be plenty of doubters and cowards and armchair critics this time around", Warren said.

Kennedy's decision to throw his support to his home state senator - and not his good friend, former Rep. Beto O'Rourke, who is considering a bid of his own - is a clear signal to fellow Democrats that she remains a serious primary contender despite a politically trying week. Edward J. Markey, along with local officials whom Warren has backed. After first winning election to the U.S. senate in 2012, Warren became one of the body's most outspoken critics of outlaw financial practices and white-collar impunity.
