KING: Live pictures there. You see Senator Elizabeth Warren doing an event in Des Moines, Iowa. She's out with another plan today while promising an even bigger policy decision will be ready soon. Education is today's focus, the Massachusetts Democrat proposals pouring billions into the funding in expansion of public schools while eliminating funding for charter schools. Senator Warren says her proposed wealth tax would pay for this new plan. The education roll out comes as Senator Warren crunches numbers on an issue central to the Democratic campaign healthcare. She has come under fire from rivals who say she's not being honest about the cost for Medicare for all. Now she promises to clearly detail the math soon.</s>SEN. ELIZABETH WARREN (D-MA) PRESIDENTIAL CANDIDATE: Right now the cost estimates on Medicare for all vary by trillions and trillions of dollars. And the different revenue streams for how to fund it, there are a lot of them. So this is something I've been working on for months and months, and it's got just a little more work until it's finished. But I want to bring this out. I will not sign a bill into law that does not reduce the cost of health care for middle class families.</s>KING: I want to bring in CNN's M.J. Lee who is out on the road with Warren in Iowa. MJ, this is going to be a huge decision rollout for her now that she's saying I've been for Bernie Sanders' Medicare for all plan, but now I'm going to essentially have my own with numbers.</s>M.J. LEE, CNN POLITICAL CORRESPONDENT: That's right, John, this is a significant announcement from Senator Warren. This is a candidate, as we've talked about a lot on your show who has a plan for nearly everything, except for the issue of health care.
