In a video announcement and email to supporters sent Monday morning, Massachusetts Sen. Elizabeth Warren announced that she was officially launching an exploratory committee to seek the 2020 Democratic nomination, making her the first candidate to officially announce in what's expected to be a "long and crowded" primary, according to the New York Times.
In her video, Warren leaned on the anti-Wall Street themes that have become a hallmark of her political career since she was elected to the Senate in 2013 after defeating moderate Republican incumbent Scott Brown. Prior to that, she had been a bankruptcy law professor at Harvard.
"I've spent my career getting to the bottom of why America's promise works for some families, but others, who work just as hard, slip through the cracks into disaster," she said in the video. "And what I've found is terrifying: these aren't cracks families are falling into, they're traps. America's middle class is under attack."
