Democratic candidates debate in Ohio

Minnesota Sen. Amy Klobuchar didn’t waste any time to go after Massachusetts Sen. Elizabeth Warren on Tuesday, using her answer on health care to raise questions about the Warren-backed "Medicare for All" single-payer health care plan.

“I appreciate Elizabeth’s work,” Klobuchar said before delivering her most direct line of any Democratic debate so far: “The difference between a plan and a pipe dream is something that you can actually get done.”

Klobuchar’s key issue with Medicare for All, a sweeping health care plan that would remake the entire health care system with an entirely government backed system, is that she doesn’t believe it can get done.

But Klobuchar also raised questions about Warren's unwillingness to answer a yes-or-no questions about whether Medicare for All will raise taxes on the middle class, something Vermont Sen. Bernie Sanders has said would happen.

“At least Bernie is being honest here,” Klobuchar said. “We owe it to the American people to tell them where we will send the invoice.”

Warren responded to her Minnesota colleague by saying, “The problem we have got right now is the overall cost of health care. You can try to spin this any way you want. I have spent my life on working on how America’s middle class has been hollowed out and how we fight back.”

There will be less work in manufacturing, less work in call centers, less work driving trucks, and more work in health care and home care and construction.

MIT Technology Review tried to track all the different reports on the effect that automation will have on the workforce. There are a lot of them. And they suggest anywhere from moderate displacement to a total workforce overhaul with varying degrees of alarm. 

One of the reports, by the McKinsey Global Institute, includes a review of how susceptible to automation different jobs might be and finds that hundreds of millions of people worldwide will have to find new jobs or learn new skills. Learning new skills can be more difficult than it sounds, as CNN has found at car plants, such as the one that closed in Lordstown, Ohio.

Sen. Elizabeth Warren has talked for more than 5 minutes. Meanwhile, Tom Steyer has spoken for less than a minute.

There are countless disagreements between the 12 Democrats on stage. Impeaching President Donald Trump is not one of them.

The first question tonight was on impeaching Trump, and nearly every Democrat on stage spoke at length about why they support moving toward impeachment proceedings against the President.

The near unanimity on impeachment highlights how many Democratic voters feel about Trump and how it behooves each presidential candidate to back ousting him from office.

Former Vice President Joe Biden was just asked about his son's business ties to foreign countries.

The Bidens have been at the center of the House impeachment inquiry, which is focusing on President Trump's attempts to pressure Ukrainian President Volodymyr Zelensky to investigate the former vice president during a July 25 phone call. 

Hunter Biden has pledged to not work for any foreign-owned companies or serve on their boards should his father be elected President.

"If it's not OK for a president's family to be involved in foreign businesses, why was it okay for your son when you were vice president?" CNN's Anderson Cooper asked Biden moments ago.

He then shifted to the impeachment inquiry into Trump.

"What I think is important is we focus on why it's so important to remove this man from office," he said.

Remember: There has been no evidence of wrongdoing by either Joe or Hunter Biden.

Businessman Tom Steyer, who is appearing tonight on the debate stage for the first time in the race, attacked President Trump, calling him the "criminal in the White House."

Steyer then went on to talk about his movement to impeach Trump.

"Two years ago, I started the need to impeach movement because I knew there was something wrong at 1600 Pennsylvania Avenue, that we did have the most corrupt President in the country and the voice and will of the American people would drag Washington to see it as a matter of right and wrong, not of political expediency. Impeaching and removing the president is something the American people are demanding," he said.

Pete Buttigieg says he is running for the 2020 Democratic nomination “to be the president that can turn the page” from Donald Trump’s presidency.

The South Bend, Indiana, mayor, asked those watching the debate tonight to imagine the day after Trump’s presidency ends.

On that day, Buttigieg said, the nation will be “vulnerable. Even more torn apart by politics than we are right now.” And the economy, climate change and other issues will still need to be addressed. “I’m running to be the president that can turn the page,” he said.

Sen. Kamala Harris said she would vote to remove President Donald Trump from office if he's impeached by the House is based on "being observant."

CNN's Anderson Cooper asked if she was "being fair to the President" when she said she'd would vote to remove him.

Harris continued: "Maya Angelou told us, 'Listen to somebody when they tell you who they are the first time.' During that election, Donald Trump told us he could shoot somebody on Fifth Avenue and get away with it. He has consistently since he won been selling out the American people."

Watch here:

The first question at tonight's debate is all about about the impeachment inquiry into President Trump.

The question: "You have said there's enough evidence for President Trump to be impeached and removed from office. But the question is, with the election one year away, why shouldn't it be the voters who determine the President's fate?"

Sen. Elizabeth Warren answered first:
