Twelve candidates took to the stage for the fourth round of Democratic presidential debate in Westerville, Ohio, Tuesday to spar over healthcare, foreign policy, impeachment, gun violence and economic inequality. CNN and New York Times moderators failed to ask a single question about the climate crisis or immigration. Massachusetts Senator Elizabeth Warren — who is now leading some national polls — repeatedly came under attack from her rivals. This is Warren on President Trump’s withdrawal of troops from northern Syria and Turkey’s ongoing deadly air and ground assault in the region.

Sen. Elizabeth Warren: “So, look, I think that we ought to get out of the Middle East. I don’t think we should have troops in the Middle East. But we have to do it the right way, the smart way. What this president has done is that he has sucked up to dictators, he has made impulsive decisions that often his own team doesn’t understand, he has cut and run on our allies, and he has enriched himself at the expense of the United States of America. In Syria, he has created a bigger-than-ever humanitarian crisis. He has helped ISIS get another foothold, a new lease on life.”

Former Vice President Joe Biden faced questioning about his son Hunter’s dealings in Ukraine and claimed he and his son “did nothing wrong,” amid ongoing impeachment proceedings against President Trump. And Bernie Sanders called for a Green New Deal, Medicare for All and defended his plan to tax the rich.

Sen. Bernie Sanders: “When you have a half a million Americans sleeping out on the street today, when you have 87 people — 87 million people uninsured or underinsured, when you have hundreds of thousands of kids who cannot afford to go to college and millions struggling with the oppressive burden of student debt, and then you also have three people owning more wealth than the bottom half of American society, that is a moral and economic outrage.”

Minnesota Congressmember Ilhan Omar announced Tuesday that she is endorsing Sanders in his bid for the presidency. Representatives Alexandria Ocasio-Cortez and Rashida Tlaib are also expected to announce their support for the Vermont senator. We’ll spend the hour on the presidential debate after headlines.
