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.

Federal ICE agents launched raids in New York City early Tuesday as part of President Trump’s illegal immigration crackdown, Homeland Security Secretary Kristi Noem said. The agents hit at least three locations in the Bronx and took at least two people into custody, sources said.

Immigration and Customs Enforcement’s stepped-up arrests continued Tuesday, with newly sworn-in Homeland Security Sec. Kristi Noem personally taking part in an operation targeting New York City. The New York operation Tuesday morning was part of a broader pattern of highly publicized ICE arrests starting last week targeting “sanctuary cities” that have passed local policies limiting cooperation with federal deportation efforts.
