The Democratic race for president gets testy ahead of the New York primary as candidates Hillary Clinton and Bernie Sanders question each others credentials. Rough Cut (no reporter narration).
ROUGH CUT (NO REPORTER NARRATION) Democratic presidential candidate Bernie Sanders is vowing to fight back against attacks from rival Hillary Clinton. Speaking at a news conference in Philadelphia, Pennsylvania, Sanders accused Clinton of attacking him first by calling him "unqualified." Tensions escalated between both candidates when Clinton, stung by a string of losses, sharply questioned Sanders' credentials and suggested he lacks expertise to implement his campaign pledge to break up big banks. Sanders shot back accusing Clinton of not being "qualified." The escalating tension between the two candidates, who for months refrained from criticizing one another outright, comes after Sanders took Wisconsin on Tuesday to notch six of the last seven contests for the Democratic nomination. Sanders continues to trail Clinton in the pledged delegates they need to win the nomination ahead of the party's July convention in Philadelphia. Clinton sees New York, a state that she represented as a U.S. senator for eight years, as home turf. Sanders, now a U.S. senator from Vermont, has reminded voters he was born and raised in New York.
