Other actions Trump may take immediately would likely rely on executive authority. Trump has vowed to sign an executive order “on Day 1” to stop federal agencies from giving automatic U.S. citizenship to the children of immigrants in the country illegally. Such an effort to end birthright citizenship would face certain legal challenges.

The president-elect would also likely resume construction of a wall along the southern border, something the Biden administration halted, and Trump could also look to reimpose policies such as the “Remain in Mexico” program, which forced potential asylum-seekers to stay in Mexico to wait out the results of their cases in U.S. immigration court.

Homan previously served as ICE director for the first 16 months of Trump’s first term, and he has been a regular presence in conservative circles advocating for Trump’s policies ever since.

“Families can be deported together,” Homan told “60 Minutes.”
