New York City mayoral candidate Zohran Mamdani defended his democratic socialism on Sunday and argued that his focus on economic issues should serve as a model for the party, even though some top Democrats have been reluctant to embrace him.

Zohran Mamdani, an outspoken critic of Israel, is the expected Democratic nominee for mayor in America's most Jewish city. That's raising concerns among some in the New York's Jewish community.

While Zohran Mamdani looks ahead to the general election, national Democrats search for lessons ahead of the midterms and Republicans see a new political target.
