BOSTON — The gloves are off. The nation’s top law enforcement official just gave Boston and other so-called “sanctuary” havens until Tuesday to stop shielding illegal immigrants — including violent offenders and child predators — or face federal consequences.

Attorney General Pam Bondi on Wednesday blasted out letters to 35 jurisdictions that limit cooperation with ICE, including Boston, Connecticut, Rhode Island, and Vermont.

“You are hereby notified that your jurisdiction has been identified as one that engages in sanctuary policies and practices that thwart federal immigration enforcement to the detriment of the interests of the United States. This ends now,” Bondi wrote.

The letters demand a response by Tuesday, August 19, confirming compliance with federal law and detailing “immediate initiatives” to scrap policies that protect criminal aliens from deportation.

On Fox News Thursday night, Bondi was blunt:

“I sent out letters to all of these mayors and to the governors, saying, ‘You must comply. We want to know what you’re doing to comply with our federal government.’ So we’re going to see.”

Boston’s sanctuary rules have already drawn national outrage after cases where ICE detainers were ignored — allowing dangerous offenders, including convicted child predators and violent criminals, to remain on the streets.

Mayor Michelle Wu, whose administration has championed sanctuary policies, shrugged off the ultimatum when pressed Friday:

“Unlike the Trump administration, Boston follows the law.”

Wu has testified before Congress insisting her policies don’t violate federal law but instead “promote trust and safety.” But the feds see it differently — pointing to repeat cases where local officials refused to turn over rapists, drug traffickers, and illegal immigrants wanted for deportation.

Bondi’s letter doesn’t spell out specific penalties if Boston and others dig in their heels — but warned that “further action” is on the table.

For Wu, it’s now a national showdown: her progressive “trust” policies versus a federal crackdown aimed at ending the sanctuary shield once and for all.
