Trump has called on ICE to expand operations to "detain and deport illegal aliens in America's largest Cities, such as Los Angeles, Chicago, and New York."

At the same time, the Trump administration has directed immigration officers to pause arrests at farms, restaurants and hotels, after Trump expressed alarm about the impact aggressive enforcement is having on those industries, according to a U.S. official familiar with the matter who spoke only on condition of anonymity.

Protests against President Trump's deportation policies have divided Republicans and Democrats on Capitol Hill and across the country. Sen. Ted Cruz, R-Texas, praised the president's decision to deploy the National Guard in California.
