A New Jersey mayor and other leading Democrats have blasted an Immigration and Customs Enforcement (ICE) raid on a worksite which they say resulted in undocumented residents as well as a U.S. citizen being "detained."

Newark Mayor Ras Baraka slammed the operation as an "egregious act" and a violation of the Fourth Amendment after agents reportedly swooped in to raid a business establishment "without producing a warrant."

Baraka said that one of those detained is a U.S. military veteran who "suffered the indignity of having the legitimacy of his military documentation questioned."

"This egregious act is in plain 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….’" Baraka wrote in a statement.

"Newark will not stand by idly while people are being unlawfully terrorized," Barak said, adding that he is "ready and willing to defend and protect civil and human rights."

It is not clear if the U.S. citizen in the Newark case was taken into custody, with an ICE spokesperson telling Fox News that the U.S. citizen was asked to produce identification. 

"U.S. Immigration and Customs Enforcement may encounter U.S. citizens while conducting field work and may request identification to establish an individual’s identity as was the case during a targeted enforcement operation at a worksite today in Newark, New Jersey," an ICE spokesperson told Fox News in relation to Thursday’s Newark operation. "This is an active investigation, and, per ICE policy, we cannot discuss ongoing investigations."

ICE raids have ramped up across the country this week as President Donald Trump looks to clamp down on illegal immigration, a key campaign promise. Trump’s "border czar" Tom Homan has said ICE agents will focus on the "worst first, public safety threats first, but no one is off the table. If they're in the country illegally, they got a problem."

New Jersey senators Cory Booker and Andy Kim joined Baraka in condemning the raid. 

"We are deeply concerned about the news of an ICE raid in Newark today. Our offices have reached out to the Department of Homeland Security to demand answers," the senators said in a joint statement.

"Actions like this one sow fear in all of our communities — and our broken immigration system requires solutions, not fear tactics. We will continue to work with Mayor Baraka and other local officials to gather more information to ensure all New Jerseyans are safe and their dignity and rights are protected."

Baraka, a progressive Democrat, has been mayor of Newark since 2014 and is running for New Jersey governor this year. He has called for a "progressive overhaul" of the blue state and his campaign agenda includes reparations, sanctuary state laws, baby bonds, and a universal basic income."

Rep. LaMonica McIver, D-N.J., also slammed the raid in a statement. 

"Already, Trump’s attacks on immigrant communities are hitting home and we will not back down," she said. "We will always fight for the dignity and rights of everyone in our district and across the country."

In the first days of the Trump administration, ICE has made more than 460 arrests of illegal immigrants, including those with criminal histories that include sexual assault, domestic violence and drugs and weapons crimes. Arrests took place across the U.S., including Illinois, Utah, California, Minnesota, New York, Florida and Maryland. 

Agents arrested nationals from a slew of countries, including Afghanistan, Angola, Bolivia, Brazil, Colombia, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Senegal and Venezuela.

A New Jersey state senator called for a limited state of emergency Tuesday as the mystery surrounding large drones flying over the Garden State continues to deepen.

"The State of New Jersey should issue a limited state of emergency banning all drones until the public receives an explanation regarding these multiple sightings," Republican New Jersey state Sen. Jon Bramnick said in a press release.

Reports of large drones flying over President-elect Trump’s Bedminster golf course and near military research sites in New Jersey have been on the rise in recent weeks. On Monday, Gov. Phil Murphy announced there were dozens of reports of drones on Sunday alone.

White House press secretary Karine Jean-Pierre said Tuesday that drones flying over New Jersey were not foreign, adding that President Biden has been made aware of the situation, and the Department of Homeland Security (DHS) and FBI are investigating.

"So, we are certainly aware. The president is aware, so we are closely tracking the activity and coordinating closely with relevant agencies, including DHS and FBI, to continue to investigate these incidents," Jean-Pierre said before adding she did not have anything else to share. "Obviously, this is something the DHS and FBI are tracking very, very closely."

When pressed if the federal government had ruled out that the drones are being controlled by foreign entities, Jean-Pierre promptly responded, "Yeah."

The Federal Aviation Administration first received reports of drone activity Nov. 18 in Morris County, which is nearly 2 miles north of Trump National Golf Club Bedminster in Somerset County.

Since then, sightings have occurred a few miles north of Bedminster in Mendham and Parsippany and other places across the Garden State.

On Monday, Murphy said there were 49 reports of drones Sunday, mostly in Hunterdon County. The Democratic governor said his numbers also included possible sightings and potentially the same drone being reported more than once.

Federal lawmakers from the state have expressed a degree of concern about the drones, regardless of the side of the aisle they stand on.

"My office has been in communication with Governor Murphy’s office and our federal agency partners," Sen. Cory Booker, D-N.J., said in a post on X. "While the drones currently pose no known threat to the public, my team and I will continue to monitor the situation closely."

Booker also penned a letter to DHS Secretary Alejandro Mayorkas, FBI Director Christopher Wray and Department of Transportation Secretary Pete Buttigieg Tuesday, seeking better transparency and a comprehensive briefing on drone activity over New Jersey.

"Over the past several weeks, there have been multiple confirmed sightings of unexplained drone activity over New Jersey communities and military installations," Booker wrote. "I recognize the need to maintain operational security of ongoing investigations and that this situation requires complex Interagency coordination. 

"However, there is a growing sense of uncertainty and urgency across the state — from constituents and local officials alike — despite assurances that the drones pose no known threats to public safety. As such, I urge you to share any relevant information about these drone sightings with the public. Without transparency, I believe that rumors, fear, and misinformation will continue to spread."

Rep. Jeff Van Drew, R-N.J., said in a statement to Fox News Digital that the recent drone sightings in New Jersey are "not only scary for residents." They point to the need for change in the state and in the U.S.

"There has been no transparency with the public, and this lack of communication is unacceptable," Van Drew said. "Constituents have been told the drones are not a threat, but no further information has been provided. People need, want and deserve answers now so they can stop worrying about their safety and privacy."

As concerns continue to mount, Robert Wheeler, the FBI's assistant director of the Critical IIncident Response Group, told Congress the federal agency knows concerningly little about the mysterious drones that have been spotted hovering over New Jersey.

When asked if Americans are at risk, Wheeler said, "There is nothing that is known that would lead me to say that, but we just don't know. And that's the concerning part."

While the FBI has been investigating the incidents, the agency has called on the public for additional information.

The FAA confirmed earlier this month that it had issued two flight restrictions in response to the questionable drone activity reported near Trump’s Bedminster golf club.

Upon request from "federal security partners," the agency issued two temporary flight restrictions.

One restriction covers an area near Solberg-Hunterdon County Airport that consists of airspace above Trump Bedminster. Flights are also banned over Picatinny Arsenal, a major U.S. Army hub in Dover, N.J., geared toward research and development via its CCDCAC armaments center.

The ban remained in place over Trump Bedminster through last week, snd the ban over Picatinny Arsenal will remain in place until Dec. 26.
