In this episode of "Up Close," we'll talk about a new era in city government. After unveiling a budget of more than $124 billion, Mayor Zohran Mamdani said the city's fiscal crisis is over. He was able to close the $5.5 billion budget deficit with help from the state, but some are worried about long-term budget deficits for the city. We'll talk to New York City's First Deputy Mayor Dean Fuleihan. We'll also discuss hantavirus and measles, as concerns are rising for both.
