Democrats talk healthcare, foreign policy, impeachment & more at 4th presidential candidate debate

Twelve candidates took to the stage for the fourth round of the Democratic presidential debate in Westerville, Ohio, Tuesday to spar over healthcare, foreign policy, impeachment, gun violence, economic inequality and more. Senator Elizabeth Warren — who is now leading some national polls — repeatedly came under attack from her rivals. In the first debate since Senator Bernie Sanders suffered a heart attack two weeks ago, the Vermont senator advocated for a Green New Deal, Medicare for All and a wealth tax. Former Vice President Joe Biden attacked the proposals of both Sanders and Warren and faced scrutiny for his son Hunter’s dealings in Ukraine.
