Elizabeth Warren is a second term senator with a scholar’s background, a New Englander with Oklahoma roots, a donut fan with an affinity for HBO dramas (specifically, “Big Little Lies” and “Ballers”).

She was a champion debater in high school who eventually found her way to teaching, then lawyering, then mixing the two as a law professor.

Later, Warren became the architect of what is now the Consumer Financial Protection Bureau, though she wasn’t picked to be its first chief when the agency opened in 2011. She entered politics instead, running for the U.S. Senate. Warren was elected in 2012, and re-elected last year.

Here is where Warren stands on some key issues:

Climate change: Supports reducing greenhouse gas emissions.

Warren favors forcing public companies to report their greenhouse gas emissions and any potential effects climate change might have on their businesses.

She issued an ambitious climate plan in September with a nod to former presidential hopeful Washington state Governor Jay Inslee, who had built his campaign on fighting global warming. She called for $3 trillion in spending over a decade to combat the problem.

Education and college costs: Wants to make public college free.

Warren has supported efforts aimed at lowering college costs. She backed a 2017 bill — introduced by Sen. Bernie Sanders, I-Vt. — that would have eliminated out tuition for many students attending public colleges. She also backed a proposal from Sen. Brian Schatz, D-Hawaii, that would have let students attend public colleges without having to take on any loans to pay for tuition, room and board, books, or other expenses.

She said in a July, 2018 speech that “this is a time of crisis” for the country’s teachers, and has supported teachers unions. This week, she tweeted support for the Los Angeles teachers who began striking on Tuesday.

Health care: Supports “Medicare for All”

Warren, a staunch supporter of the Affordable Care Act, has also advocated for further action to ease health care costs and slash drug prices. In 2018, she proposed limiting insurer profits while expanding health care subsidies and tax credits.

She supports “Medicare for All” as a way to achieve universal health care. Recently she has said her plan would take three years to implement, a concession that was slammed by progressives.

Trade: Supports renegotiating NAFTA. Opposes President Donald Trump’s trade policies.

Warren is a critic of the North American Free Trade Agreement, or NAFTA, and blames U.S. trade policy more generally for widening economic inequality in the country.

While she favors renegotiating NAFTA, she argues the deal Trump struck with Canada and Mexico in 2018 will have few benefits for American workers.

Warren has called Trump’s economic policies “beyond inept,” and has argued that the Trump administration’s tariffs are hurting U.S. farms and businesses.

Afghanistan, Iraq and Syria: U.S. should withdraw troops from those countries.

Warren, a member of the Senate Armed Services Committee, supports reducing the U.S. military’s presence in some global hotspots. Last November, she called for the immediate withdrawal of American troops from Afghanistan.

Warren also says the U.S. should withdraw service members from Iraq and Syria, though she has not gone into detail about what timetables she would support for those withdrawals.
