AG Andrea Campbell says Massachusetts is ready if the National Guard is deployed to the Bay State, adding that her office is “drafting paperwork” that she hopes it never has to file against President Donald Trump.

The attorney general’s comments mark the firmest stance yet from a Bay State official on what kind of coordination or preparations are being made in the case Trump tries to deploy troops in Massachusetts.

Trump has deployed National Guard units to cities he argues are dealing with high crime or are epicenters of federal immigration activity, even as governors and mayors have largely voiced opposition to their arrival.

“We are prepared if they were to come,” Campbell said on GBH’s Boston Public Radio on Tuesday. “Of course, I hope they don’t, because the narrative they’re suggesting is that they would come here to promote public safety, and we are doing just fine.

“If anything,” the AG continued, “we’re seeing in other communities across the country is that they’re eroding public safety and trust between law enforcement and the community. In addition to that, they’re perpetuating fear.”

Campbell said her office is engaging with the National Guard, Gov. Maura Healey’s office, the state Legislature, law enforcement, and “every stakeholder” available over how the state would respond to a potential deployment.

The AG added that she’s personally spoken with her counterparts in California, Illinois and Oregon, states where Trump has threatened to deploy the National Guard to combat what he describes as lawlessness.

Trump continues to face legal challenges in areas where he has looked to deploy troops.

Courts in Tennessee and West Virginia heard arguments Monday challenging the deployment of their states’ National Guard troops to patrol the streets of Memphis and Washington, D.C.

Since their arrival on Oct. 10, National Guard troops have been patrolling neighborhoods and commercial areas of Memphis, wearing fatigues and protective vests that say “military police.” Officials have said Guard members, who are armed, have no arrest power.

West Virginia is among several states that sent troops to Washington, D.C., to support Trump’s crime-fighting efforts. Last month, a West Virginia judge asked attorneys for the state to address whether Gov. Patrick Morrisey’s deployment of up to 300 Guard members to the nation’s capital in August was legal.

The Bay State AG’s Office has filed 41 complaints against the Trump administration since the president regained office in January. Campbell made clear that another may be coming if Trump tries to deploy troops here.

“Any time you file a lawsuit, it takes a lot of human capital resources and work,” the AG said. “And frankly, you have to be prepared beforehand, so we hope we never have to file anything.”

Healey said last month that sending the National Guard to major U.S. cities is a “waste of resources,” but the first-term Democrat declined to say if she was coordinating with any local officials or preparing any action in case Trump attempted to conduct a deployment in Massachusetts.

Bay State Congressman Jim McGovern told the Herald last month that he had spoken to the Healey administration about a possible National Guard deployment.

Campbell said troops are designed to handle a “major flood, a major emergency” in the state. She added that she doesn’t know how equipped the National Guard is to accomplish what Trump wants it to.

“They’re not necessarily trained to show up in the city of Boston,” she said, “or the municipalities here in Massachusetts, to promote public safety, to investigate crimes, to respond appropriately.”
