In New York, Clinton reiterated her critique of Sanders' 'Medicare for all' plan, saying it would force Congress to 'start all over again' on health care reform.
She also rebuked Republican Donald Trump for saying that women should be 'punished' for having an abortion, comments he quickly backtracked from.
Clinton also noted an MSNBC interview in which Sanders suggested Trump's comments were a distraction from serious issues. 'To me this is a very serious issue and it is a very serious discussion,' Clinton said.
Clinton's event held some nostalgia for the former first lady and secretary of state, who formally launched her Senate campaign on the campus in February 2000 and lives in nearby Chappaqua.
She was introduced by Rep. Nita Lowey of New York, who noted that Clinton was her 'constituent'.
