A Senate Republican has introduced legislation aimed at blocking federal funding to cities that enforce international arrest warrants against officials from allied countries. This move comes after New York Mayor-elect Zohran Mamdani reaffirmed his intention to arrest Israeli Prime Minister Benjamin Netanyahu if an international court warrant is upheld. The proposed bill, called the American Allies Protection Act, would withhold Department of Justice grants from cities that cooperate with such warrants, unless the president determines it is necessary for national security. The debate highlights growing tensions over international law and U.S. alliances, with critics warning of potential harm to diplomatic relationships.
