The funds given to the federal government come from the people at the local level. The federal government works for the states and local government, not the other way around. "Sanctuary City" simply means that local resources will not be used to do the job of federal agencies like ICE. People who think the "Sanctuary City" means that the local government is going to hide or protect wanted criminals really need to do their research. The federal government withholding funds that belong to local and state governments would be criminal. This is 100% federal government overreach.
