In a Truth Social post, Trump urged ICE officers to do everything they can to carry out what he described as the "largest mass deportation operation of illegal aliens in history," particularly in cities like Los Angeles, Chicago, and New York, where many illegal immigrants are concentrated.

Protests have erupted in those cities in recent days, with thousands of protesters marching toward ICE facilities in protest against federal immigration enforcement efforts. In some locations, the protests resulted in injuries as demonstrators clashed with law enforcement.

Trump noted that ICE officers face violence and threats from opponents of the operation, but emphasized that nothing will deter his administration from fulfilling its mandate.

The president said he had directed his administration to put "every resource possible behind this effort," while offering his unwavering support for ICE in executing the mission.

"Our federal government will continue to be focused on the remigration of aliens to the places from where they came, and preventing the admission of anyone who undermines the domestic tranquility of the United States," he stated.

On June 12, the Department of Justice (DOJ) filed a lawsuit against the state of New York over its state policies that prevent federal immigration officials from arresting immigrants at courthouses.

The suit was the latest in a series of actions the DOJ has brought, alleging that sanctuary jurisdictions thwart federal authority. In New York state, the department has filed two other lawsuits: one challenging the city of Rochester and another targeting the state's restriction on sharing information through the Department of Motor Vehicles.

"Lawless sanctuary city policies are the root cause of the violence that Americans have seen in California, and New York State is similarly employing sanctuary city policies to prevent illegal aliens from apprehension," Attorney General Pamela Bondi said in a statement.

Trump suggested on June 12 that his administration would issue an order tackling the issue of illegal immigrants who work in agriculture, hospitality, and other industries, stating that his immigration policy could impact the workforce in these sectors.
