Elizabeth Warren: Am I worried about Trump? No, he might be in jail when Election Day comes.

Senator Elizabeth Warren is firing back at President Donald Trump.

On her first full day of campaigning as an official candidate for President of the United States, Warren said that Trump might not even be able to take the office, because he'd be in jail.

"By the time we get to 2020, Donald Trump may not even be President," Warren said to voters in Cedar Rapids, Iowa, in front of the Veterans Memorial Building. "In fact, he may not even be a free person."

Warren is brushing off criticisms of "Pocahontas" and misrepresenting her Native American heritage when she was a young woman. She talked to the crowd like nothing in the world was going to stop her on the campaign:

"Every day, there's a racist tweet, a hateful tweet, something really dark and ugly," Warren said of Trump. "And what are we, as candidates, as activists, the press, going to do about it? Are we going to let him use those to divide us?"

She laid out her game plan moving forward:

"Here's how I see it: Donald Trump is not the only problem we've got. Yeah. Donald Trump is the symptom of a badly broken system," Warren said. "So, our job as we start rolling into the next election is not just to respond on a daily basis. It's to talk about what we understand is broken in this country, talk about what needs to be done to change it and talk about how we're going to do that, because that is not only how we win, it's how we make the change we need to make."

Warren was attacked by Representative Liz Cheney, former Vice President Dick Cheney's oldest daughter on early Sunday morning just before she gave the rally.

"She has made herself a laughingstock. I wonder if there is anyone around her telling her that this is isn't going to work."

Warren is known for her fight against Wall Street and the big banks. If elected, her top priority is to end the wealthy's influence on Congress.
