A ‘Personality conflict’ is shaking up North Las Vegas City Hall. City Manager Qiong Liu is negotiating her resignation. It comes one day after she insisted on firing Assistant City Manager Ryann Juden amid long-simmering tensions. Mayor John Lee insisted Juden will not be fired. The dispute reportedly stemmed from a disagreement over how to fund infrastructure projects at the Apex Industrial Park. Liu said appointing Juden was “the biggest mistake that I have made over the past 4-plus years leading the executive team.”
