Elizabeth Warren has been in the senate for not quite four years,курсанты военного училища устроили би порнографию but she's got a long list of credentials. 

She is a fist-pumping rabble-rouser who knows how to work a crowd into shouts of approval. She's also an academic, and one of the foremost U.S. experts on bankruptcy and consumer protection. She's a woman who used to vote Republican but is now a hero of left-leaning Democrats, and who has stood up to President Barack Obama and attacked Wall Street. 

And now she's Hillary Clinton's not-so-secret weapon against Donald Trump.

What's Warren's background?

Prior to entering politics, Warren was a Harvard University law professor. She also taught at the University of Texas, the University of Michigan, the University of Pennsylvania and other schools. Before her work in academia, and before obtaining her law degree at Rutgers University, she received her undergraduate degree in speech pathology from the University of Houston. She was the first member of her immediate family to graduate from college. Warren worked with children with disabilities in public schools before shifting her focus to the law.

How did Warren get involved in politics?

Warren became a force in bankruptcy law, earning her an advisory role on the National Bankruptcy Review Commission in 1995, as well as other committees and conferences that develop bankruptcy law. 

In 2008, as the American economy struggled to get back on its feet amid financial crisis, Sen. Harry Reid appointed Warren to head the Congressional Oversight Panel that would supervise the bank bailout known as the Troubled Asset Relief Program. 

In 2010, Obama appointed Warren to lead a new Consumer Financial Protection Bureau, but Republicans were vehemently against her, so the president had to look elsewhere. The following year, Warren decided to run for a seat in the Massachusetts Senate, and in 2012, she defeated the Republican incumbent, Scott Brown. 

Why does Warren get under Trump's skin?

Warren quickly rose to become one of the most prominent Democratic senators in the country. There was even significant speculation about whether she'd run for president in 2016. 

She declined, but she's now surrounded by even more speculation as a possible vice presidential pick for Clinton's campaign. And as a new Clinton ally, Warren has launched all kinds of tirades against Trump, the presumptive Republican nominee for president.

Trump, who is not known for letting criticism roll off his back, has taken to swatting back at Warren.

Why does Trump call Warren "Pocahontas?"

News outlets covering her 2012 Senate race dug into Warren's supposed Cherokee heritage, because she couldn't prove her claims to Native American ancestry. 

Warren's opponent seized on that, accusing her of making up a minority heritage to obtain high-profile positions with law schools. That was never proven, either, though the idea of Warren as a liar has stuck in some circles. 

Trump began calling her "Pocahontas" to remind the world of the ancestry flap from four years ago.

Of course, Warren claimed to be Cherokee, and Pocahontas was Powhatan, but that bit of information appears to be neither here nor there for Trump.

Is she going to be a vice presidential candidate? 

If she winds up being Clinton's choice for vice president, Warren will have taken one of the more interesting paths to get there. 

Warren has said she used to vote Republican because they seemed to be the more "principled" economic party until the turn of a new century. 

Warren used Clinton's smarts against her in a 2004 critique of the candidate, and she blasted Obama in 2015 over lack of transparency in the Trans-Pacific Partnership deal. 

But she has galvanized the left, a part of the Democratic Party that Clinton wants to bring under her wing. Despite her circuitous route to the center of American politics, Clinton may find that there is no one better equipped to stand by her.
