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.

New York Gov. Kathy Hochul said the state is willing to cooperate with the Trump administration’s efforts to deport undocumented migrants suspected of entering the country illegally — but only under certain circumstances.

New York is now one of the U.S. cities being targeted by federal officials as part of the Trump administration's crackdown on illegal immigration.

The state will cooperate with federal officials when a person is suspected of crossing the border without checking into an official port of entry, among other cases.
