Host of HBO's Real Time, Bill Maher and Sen. Bernie Sanders (I-VT) discuss his Presidential campaign and what "socialism" really means and how he plans to fund his social and economic policies.



Maher went down a litany of Sanders' initiatives -- free healthcare, free public higher education, increasing Social Security benefits -- and asked the presidential candidate how he would pay for his agenda.



Maher grilled Sanders on the economic viability of his "Medicare for all" healthcare plan.



"If you are saying that the government is going to pick up the tab but not make the insurance companies, the hospitals and the doctors not gouge people, then we are going to break the budget," Maher told Sanders.
