United States Conference of Mayors


Chair: Christian Mesa

Topic A: Immigration and Sanctuary Cities

Topic B: The Growing Threat of Climate Change

The United States Conference of Mayors is the official non-partisan organization of large cities that promotes urban policy on issues such as terrorism, transportation, and domestic law enforcement. The Conference also seeks to develop intercity relationships, ensure that federal policies meet urban needs, and provide mayors the tools to lead their cities more effectively. During its annual meetings, mayors from across the nation collaborate to create and adopt policy positions that collectively represent the views of America's mayors -- and influence decisions by Congress and the President. As representatives and leaders of the nation's populous cities, delegates will be tasked to address how cities can respond to growing threats from climate change, as well as challenges related to immigration and sanctuary cities.
