Warren, Buttigieg spar over health care costs

Warren, Buttigieg spar over health care costs-thehill: Sen. Elizabeth Warren (D-MA) and former South Bend, Ind., Mayor Pete Buttigieg tangled over the costs associated with their health care proposals at the Democratic debate. Warren, who supports "Medicare for All," said Buttigieg's plan to create a public option costs less because it's only a "small improvement" over the current system.
