Gimenez signed an order today demanding that Miami-Dade County's Department of Corrections and Rehabilitation comply with every aspect of Trump's plan.
"Yesterday, January 25, 2017, President Donald J. Trump issued Executive Order: Enhancing Public Safety in the Interior of the United States," Gimenez wrote to Daniel Junior, the county's interim corrections director. "In light of the provisions of the Executive Order, I direct you and your staff to honor all immigration detainer requests received from the Department of Homeland Security."
