SCOTUS has repeatedly ruled that the executive branch cannot deny states funding for failure to meet conditions that were not part of the funding bill/law. I.e., Obama couldn’t deny Medicare funding to a state that failed to expand coverage, because that wasn’t part of the law (the ACA) as written. See: National Federation of Independent Business v. Sebelius. The current law funding states doesn’t contain any requirements for states to help with immigration enforcement (Mostly because of 10A). Therefore, there is no legal recourse for the administration to penalize states by withholding funding. Also, the federal government funds the states with a formula, based on population, poverty, unemployment, transportation infrastructure, etc. It cannot make arbitrary and capricious decisions to penalize states.
