The Boston operation comes as Chicago braces for an immigration crackdown surge.
U.S. Immigration and Customs Enforcement (ICE) has launched an immigration enforcement operation in Boston, dubbed Patriot 2.0, according to a spokesperson for the Department of Homeland Security.
Meanwhile, President Donald Trump on Saturday posted a "Apocalypse Now"-themed post, telling officials that "Chicago is about to find out why it's called the Department of WAR." Trump signed an executive order Friday to change the name of the Department of Defense to the Department of War, though the official name change requires the approval of Congress.
Trump plans to attend the U.S. Open men's final tennis match in New York on Sunday, the White House said.
The vice president took to X to slam senators who grilled Health and Human Services Secretary Robert F. Kennedy Jr. during Thursday's hearing.
Vice President JD Vance, who did not name anyone specifically, accused the senators of "trying to lecture and 'gotcha' Bobby Kennedy," and used vulgarity to criticize them.
Two Republican senators -- both doctors -- sidestepped questions from ABC News asking if they have confidence in Robert F. Kennedy Jr. to continue leading HHS, as Thursday's hearing wrapped up.
When asked if RFK Jr. assuaged his concerns or if the HHS secretary should resign, Sen. Bill Cassidy referred to his questioning in the hearing.
Cassidy pointedly asked the secretary about his COVID-19 vaccine policies.
Sen. John Barrasso, the No. 2 Republican in the Senate and a doctor as well, also avoided questions about his confidence in RFK Jr.
"I have confidence in what the president of the United States is doing and I would not second guess it," he told ABC News.

Trump signed an executive order implementing his trade deal with Japan, according to the White House.
The deal was reached in July but had to be finalized by both the U.S. and Japan.
“Under the Agreement, the United States will apply a baseline 15 percent tariff on nearly all Japanese imports entering the United States, alongside separate sector-specific treatment for automobiles and automobile parts; aerospace products; generic pharmaceuticals; and natural resources that are not naturally available or produced in the United States," the order says.

Attorneys representing former CDC Director Susan Monarez pushed back on Kennedy's narrative of the events that led to her firing last week.
The HHS secretary claimed in a hearing on Thursday, “I told her she had to resign because I asked her, 'Are you a trustworthy person?' And she said, 'No.'”
Monarez's lawyers call Kennedy's claim "false" and "patently ridiculous."
"Dr. Monarez stands by what she said in her op-ed in The Wall Street Journal, would repeat it all under oath and continues to support the vision she outlined at her confirmation hearing that science will control her decisions," her lawyers Mark Zaid and Abbe Lowell said in a statement.
"I was told to preapprove the recommendations of a vaccine advisory panel newly filled with people who have publicly expressed antivaccine rhetoric," Monarez wrote in her op-ed published Thursday.
Monarez was also asked to fire senior CDC officials, according to officials with knowledge of the situation.
