As at least 13 million undocumented immigrants remain in the US, incoming border czar Tom Homan plans to use federal funding cuts as leverage against states resisting mass deportation efforts. Democratic-led jurisdictions such as California and New Mexico are preparing to legally challenge these actions. Homan emphasizes prioritizing public safety and national security threats, and suggests undocumented immigrants self-deport to avoid future legal consequences. Current data shows unlawful border crossings near historic lows, raising questions about the feasibility of Trump's aggressive immigration agenda amid pushback from state officials.
