White House Press Secretary Karoline Leavitt said Tuesday the first flights of undocumented immigrants from the U.S. to Guantánamo Bay in Cuba were underway—following an escalation of arrests across the country as part of what President Donald Trump has promised would be the “largest deportation operation” in U.S. history.

Another point of concern is the Trump administration's promise of "mass deportation" efforts across the country. According to local immigration attorneys, much of what Trump wants to do would require a significant amount of resources — financially, staffing-wise and spatially.
