Shortly after President Donald Trump took office promising an immigration crackdown, 
Gimenez reversed a 2013 county policy and ordered Miami-Dade jails to begin honoring requests by immigration officers to extend the detentions of people in local custody who are also being sought for possible deportation.
Miami-Dade is the only large jurisdiction known to have made that kind of change, which the County Commission endorsed in February. As a result, it has been assumed 
Miami-Dade would be shielded from any loss of federal funds the Trump administration engineered as part of a broader effort to punish communities not cooperating on immigration detentions.
