U.S. President Donald Trump's top homeland security official joined officers as they carried out an immigration arrest in New York City on Tuesday, the latest effort to promote Trump's nationwide crackdown as enforcement has intensified in recent days.

On Monday, the Florida Highway Patrol conducted a joint operation with federal immigration officers in Jefferson County to round up 12 people believed to be in the country illegally, one of a number of raids performed around the country as the Trump administration ramps up its plans for mass deportation.

In a display of force aimed at increasing arrests and generating publicity, the administration targeted the nation’s largest city, where sanctuary policies limit cooperation with ICE.
