The Trump administration also floated the idea of using the National Guard troops of about a dozen states deemed to have an 'illegals' problem.  Fortunately the governors of most of those states were not at all enthusiastic.  That would have been Trump's 15,000 ICE troops on the cheap, but now he has to recruit and pay for them.  Hopefully Congress refuses to pay the tab.  Realistically, a GOP congress let Bush run an unfunded war, so I don't have a great deal of hope.
