US President Donald Trump warned NYC Mayoral candidate Zohran Mamdani to "better behave" after Mamdani pledged that if elected, he'd have Israeli PM Benjamin Netanyahu arrested if he visits New York. "[Mamdani is] going through...honeymoon right now, [and] he might [win], but it all comes through...White House," Trump said. Mamdani has been a vocal critic of Israel's actions in Gaza.
