Newark Mayor Ras J. Baraka issued a statement late Thursday afternoon denouncing the raid as an “egregious act” conducted without a warrant and in violation of the Fourth Amendment of the U.S. Constitution, which guarantees “the right of the people be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.”

President Donald Trump signed more executive orders aimed at shutting down the southern border, but the details on how migrants would be blocked from crossing remain unclear.

In a significant shift in U.S. immigration policy, President Donald Trump has authorized Immigration and Customs Enforcement to carry out arrests in “sensitive” locations such as schools and churches.

Agents made 538 arrests during workplace raids across the Northeast Thursday, U.S. Immigration and Customs Enforcement said.

The largest massive deportation operation in history is well underway,” the White House press secretary wrote on social media.

ICE agents often operate in the community without notifying local authorities and may wear uniforms resembling those of local police, creating potential confusion, Napa’s police chief said.

The president’s Day 1 actions included directives that fly in the face of legal limits on involving the military in domestic operations and the constitutional guarantee of birthright citizenship.

The Trump administration rescinded a policy that limited immigration enforcement actions in or near “sensitive locations,” such as schools, playgrounds, child care centers and bus stops.

Several districts cited recent guidelines issued by New York officials that outlined how schools should react to immigration visits.

President Donald Trump has promised sweeping mass deportations in communities across the country, and the U.S. Department of Justice recently threatened to prosecute local officials standing in the way of immigration enforcement.

The directive allows federal law enforcement agents to carry out immigration-related enforcement actions that are usually reserved for officials under DHS.
