Biden, the current front-runner in the nomination battle, appeared on Friday evening to take a jab at Sen. Kamala Harris of California over a lack of straightforwardness on her support for Medicare for All. At the same time, he singled out Sen. Bernie Sanders for being honest about the ramifications of implementing the single-payer healthcare plan.

“Bernie’s been very honest about it. He said you’re going to have to raise taxes on the middle class. He said it’s going to end all private insurance. I mean, he’s been straightforward about it. And he’s making his case,” Biden said after an impromptu gaggle with reporters following a stop at an ice cream shop in New Hampshire, the state that holds the first primary in the White House race.
