BOSTON — The head of U.S. Immigration and Customs Enforcement on Monday defended his tactics against criticism that authorities are being too heavy-handed as they ramp up arrests toward President Donald Trump’s promises of mass deportations.

San Diego Mayor Todd Gloria said he was “deeply upset” by an ICE operation at a popular Italian restaurant just before the dinner rush on Friday. A chaotic showdown unfolded outside as customers and witnesses shouted, smoke filled the air, and agents wore heavy tactical gear to face an angry crowd.

Todd Lyons, ICE’s acting director, turned emotional when asked to explain why officials wear masks. He said some have received death threats and been harassed online.

“I’m sorry if people are offended by them wearing masks, but I’m not going to let my officers and agents go out there and put their lives on the line, their family on the line because people don’t like what immigration enforcement is,” he said at a news conference in Boston to announce nearly 1,500 arrests in the region as part of a month-long “surge operation.”

Lyons was leaving the room when a reporter asked him about the masks. He returned to the podium.

“Is that the issue here that we’re just upset about the masks?” he asked. “Or is anyone upset about the fact that ICE officers’ families were labeled terrorists?”

Lyons may have been referring to comments by San Diego Councilman Sean Elo-Rivera, who called ICE officers “terrorists” after Friday’s restaurant raid. “This isn’t safety. It’s state-sponsored terrorism,” Elo-Rivera wrote on Instagram.

The Department of Homeland Security reposted Elo-Rivera’s message, saying that likening ICE to terrorists was “sickening.” The councilman stuck by his comments on Monday.

Other elected officials, such as Gloria and U.S. Rep. Scott Peters of San Diego, both Democrats, were more muted but also sharply critical of ICE and the Republican White House.

“Federal actions like these are billed as a public safety measure, but it had the complete opposite effect. What we saw undermines trust and creates fear in our community,” Gloria said.

ICE said Monday that the operation at Buona Forchetta, an anchor of San Diego’s trendy South Park neighborhood, resulted in four arrests of people in the U.S. illegally. Authorities executed criminal search warrants for illegal hiring and making false statements when the crowd “became unruly,” prompting them to use flash-bang devices.

“When gatherings like these are formed, it not only places law enforcement in danger but also the demonstrators/onlookers attempting to impede law enforcement activity,” ICE said in a statement.

The owners said they were closing their restaurants in Southern California for two days.

“We wish we could find stronger words, but the truth is we are heartbroken,” the owners said in a statement. “The traumatic incident involving a federal enforcement operation at our original and beloved South Park location has left a mark on all of us. A wound that is still raw, still echoing in our kitchens, our dining rooms, and our hearts.”

Lyons said in an interview on Fox & Friends Sunday that ICE was averaging about 1,600 arrests a day, a sharp increase from previous data that showed 78,155 arrests between Jan. 20 and May 19 — a daily average of 656. He said ICE can and will do more.

Stephen Miller, the key architect of Trump’s immigration policy, last week set a goal of 3,000 arrests a day and said the number could go higher. That pace would be a huge challenge with current funding. ICE housed an average of more than 46,000 detainees during the first half of May, already above its budgeted capacity.

Lyons said operations like the surge in Massachusetts wouldn’t be necessary if “sanctuary cities would change their policy.” There’s no legal definition for sanctuary city policies, but they generally limit cooperation by local law enforcement with federal immigration officers. Homeland Security published a list of more than 500 sanctuary jurisdictions but removed it from its website after criticism that it contained inaccuracies, even from its allies.

Lyons stood near a poster board with mug shots of unnamed immigrants. A full list of those arrested was not available, nor was information about the crimes specific individuals are accused of committing.

Lyons called them “dangerous criminals” who are “terrorizing family, friends and our neighbors.”

State, local and federal authorities participated in a raid Saturday at a South Carolina nightclub that officials said was popular with drug dealers, resulting in the arrests of 66 people who were in the country illegally. Cardell Morant, special agent in charge of Homeland Security Investigations in South Carolina and North Carolina, said the 3 a.m. operations came during a “cartel after-party.”

Officials did not release additional details about the charges being faced by those who were arrested during the raid in Charleston County.

House Minority Leader Hakeem Jeffries decried what he called the “toxic bait-and-switch” of President Donald Trump‘s leadership on ABC News’ “This Week” on Sunday.

“Donald Trump and Republicans consistently promised that they were going to lower the high cost of living, and they’ve done the exact opposite,” Jeffries told co-anchor Jonathan Karl. “They’ve shown no interest in lowering costs in the United States of America, which are too high.”

Jeffries said the Trump administration has “broken their promise” to Americans, and accused them of having “no interest in improving the quality of life of hard working American taxpayers.”

“Instead, what they’re trying to do while they distract the American people is to jam the GOP tax scam down the throats of people all across this country, all in service of massive tax cuts for their billionaire donors and wealthy corporations,” he continued. “It’s a toxic bait-and-switch that is underway, and we will continue to push back forcefully.”

While Jeffries blasted his Republican counterparts, Speaker Mike Johnson has asserted Democrats are “flailing,” saying they “have no clear leader.”

But Democratic Rep. Don Beyer of Virginia has also suggested the party is without a clear leader. “We’re still looking for that national spokesperson,” Beyer told Axios. “And it could be that Hakeem becomes that national voice. … It hasn’t happened yet.”

Asked to respond to that, Jeffries said it was his “honor to be House Democratic leader.”

“We’re going to continue to work together in an all-hands-on-deck effort to push back against the far-right extremism that is being unleashed on this country with record velocity,” he said. “We’re pushing back forcefully against those efforts every day, every week, every month, every year, and that will continue.”

During the interview, Jeffries also said he was “very concerned” by the Department of Justice dropping the bribery case against New York Mayor Eric Adams.

“Mayor Adams has a responsibility to convince the people of New York City that he will be able to continue to govern in a manner that puts their best interests first at all times, and that he’s not simply taking orders from a Trump administration, a Trump Department of Justice, or Trump officials who do not have the best interests of the city of New York at heart,” said Jeffries, who represents a Brooklyn district in the House.

“This Department of Justice is not promoting law and order — it’s promoting lawlessness and disorder,” he added. “And that’s been consistent with what we’ve seen from the Trump administration from the very beginning.”

As an example of this, Jeffries pointed to the mass pardoning of convicted Jan. 6 rioters “who attacked and brutally beat police officers and then were released back into communities all across the country, threatening public safety.”

Many of the pardoned rioters “have extensive criminal records for things like domestic violence, weapons charges that are serious and rape,” he added.

“This is not an administration that is committed to the safety of the American people. They continue to undermine it and flood the zone with chaos,” he said.
