Former President Donald Trump targeted undocumented immigrants in a speech in Nevada on Sunday as he continues to lean into anti-immigrant rhetoric ahead of early Republican presidential nominating contests. At a rally in Reno, Trump stoked fears about migrants crossing the US-Mexico border and cited examples of undocumented immigrants committing violent crimes. He claimed migrants were "invading" the US from prisons and "mental institutions" in other countries. Trump reiterated promises to conduct the "largest deportation operation in American history" if elected again.
