Michell Wu, mayor of sanctuary Boston, should remind Congress in her testimony before the House Oversight Committee  Wednesday that it falls on the anniversary of the Boston Massacre.

The committee, headed by Republican Rep. James Comer of Kentucky, is investigating sanctuary cities, of which Boston is one.

Also scheduled to testify are New York Mayor Eric Adams, Chicago Mayor Brandon Johnson and Denver Mayor Mike Johnston.

President Donald Trump has threatened to withhold federal funds from sanctuary cities which interfere with the “lawful exercise of Federal law enforcement operations,” which means the arrest and deportation of criminal illegal immigrants.

Far-fetched as it appears, Wu could stand up to Trump the way Boston colonialists stood up to the King George and the British.

Other than that, she does not have much going for her since the committee has already condemned Boston and the other three cities for “their abject failure to comply with federal law.”

The Boston Massacre was the incident on March 5, 1770, when a contingent of harassed British soldiers opened fire on a group of oppressed and angry Boston colonialists on King Street behind the old State House. They were protesting British rule.

Five Colonists were killed and several more wounded.

The killings helped ignite the Revolutionary War that began following the April 19, 1775, skirmishes called the Battle of Lexington and Concord and the vastly bloodier June 17, 1775, Battle of Bunker Hill in Charlestown.

Warming up, Wu could invite Comer and the committee to walk Boston’s Freedom Trail and visit the massacre site. It would put things in perspective on the eve of the 250th anniversary of the signing of the Declaration of Independence July 4, 1776.

That anniversary will be a big deal in Boston, the home of the revolutionaries, many of whom were immigrants, legal or otherwise. The British thought they were criminals.

The Revolutionary War, or the War of Independence, was fought to throw off oppressive British law and control of the Colonies. Boston in many ways was the center of the rebellion against British rule and law.

Now, all these years later, Boston is in many ways the center of the rebellion against United States rule and law when it comes to protecting illegal immigrants, particularly against Trump’s directive to withhold federal funds from sanctuary cities that interfere or impede ICE operations.

Wu, the daughter of Taiwanese immigrants, falls back on the Boston Trust Act which she voted for as a city councilor and is supporting as mayor.

The act prohibits Boston cops from asking individuals about their immigration status, sharing information with ICE, making arrests solely on ICE administrative warrants, performing the function of federal immigration officers as well as transferring individuals to ICE custody.

Trump’s border czar Tom Homan, who has promised to bring “hell” to Boston, and Comer may not like the act, but it seems to be all right with the Boston Police Patrolman’s Association. It endorsed Wu for mayor Thursday over challenger Josh Kraft.

The endorsement is not only a boost to her campaign for re-election, but it arms her with a valuable talking point when she testifies Wednesday before Comer’s committee.

She will need it even though the Massachusetts Supreme Judicial Court has ruled that “court officers (and presumably cops) have no authority to arrest and hold individuals solely on the bases of an ICE warrant.

So, if the cops are with her, who can be against?

Well, President Trump for one. He has vowed to withhold federal funds from sanctuary cities “which seek to interfere with the enforcement of Federal law enforcement operations.”

Which is no doubt why Comer, in his letter requesting Wu’s testimony, made it clear that Wu will not be addressing the Boston City Council, but a committee determined to crack down on sanctuary cities.

The letter said, “It is imperative that federal immigration law is enforced and that criminal aliens are swiftly removed from our communities.”

The president has his law and the mayor has hers. It’s a clash.

It could be a massacre.
