Donald Trump spread dangerously exaggerated claims about migrants having “invaded” and “conquered” Aurora, Colorado, intensifying his anti-immigration rhetoric.

Addressing thousands of supporters in a cavernous Aurora ballroom, former President Donald Trump on Friday described the migrant challenges faced by his host city in near-apocalyptic terms. His solutions to what he portrayed as lawlessness amid a national crime wave by undocumented immigrants — by exaggerating the “limited” problems acknowledged by Aurora city officials and seizing on isolated incidents elsewhere — were equally stark.

The Aurora he’s talking about is one the people of Colorado have never heard of,” Colorado Gov. Jared Polis said Friday.
