ROME (AP) — Pope Francis said Donald Trump’s plans to impose mass deportations of immigrants would be a “disgrace,” as he weighed in on the incoming U.S. president’s pledges nearly a decade after calling him “not Christian” for wanting to build a wall along the U.S.-Mexican border.

Mexican President Claudia Sheinbaum is pulling out all the stops to support the roughly 5 million undocumented Mexicans living in the U.S.

The new administration could use the existing system of federal agents, local police and jails to funnel more people into the deportation pipeline.

House Speaker Mike Johnson (R-LA), a fiscal hawk, agreed to support President-elect Donald Trump's mass deportation plan "no matter what the cost." During a Sunday interview on Meet the Press, host Kristen Welker noted that mass deportations could cost the American taxpayer "trillions" of dollars.

Schools near the border say it’s hard to prepare for the unknown. Immigration advocates say they should help communities understand students’ rights.
