Gov. Mikie Sherrill is nearing her first 100 days in office in New Jersey after an early stretch defined by rapid executive action and frequent clashes with the White House. Sherrill began her term with more than a dozen executive orders, including a move to freeze high electric rates, as her administration faced multiple snowstorms in its opening weeks. After the weather-related challenges, legal fights and lawsuits with Washington became a central focus of the governor’s early months.
