Denver plans to close four migrant shelters over the next month, potentially saving up to $60 million this year and reducing the need for budget cuts, Mayor Mike Johnston said Wednesday. The closures will leave three hotel shelters open for migrants, along with a couple congregate shelter spaces. But Johnston warned the closure plan could change if the city sees massive surges of arrivals and again has to increase its shelter space and migrant services. He also took issue with claims this week by Aurora City Council members that migrants were being bused into their city. In Denver, city departments have started making budget cuts at Johnston’s direction to offset the costs of migrant services.
