The lefty attorney general of Oregon has rolled out a new program to help illegal migrants in the sanctuary state thwart ICE ahead of President-elect Donald Trump’s promised mass deportations.

Ellen Rosenblum’s recent new guide, titled the “Sanctuary Promise Community Toolkit,” offers advice to illegal immigrants on what to say and do if ICE or other immigration authorities show up.

For the question, “How do I prepare myself and my family for encounters with ICE?” the answer includes legal guidance from the American Civil Liberties Union: “do not open the door, ask to see a warrant signed by a judge, tell them you do not consent to them being at your home and tell them please leave.”

In answer to the question, “Is there a place I can call to report ICE or other federal immigration authorities active right now in my community?” the Oregon Department of Justice lists contact information for local nonprofits that work to warn migrants about federal operations.

There are also multiple sections on how to report anyone who is suspected of violating Oregon’s sanctuary law and working with federal immigration authorities.

One section advises locals that they can sue any state or local agency that they suspect of violating sanctuary law.

However, the “Sanctuary Promise” guide admits that state laws can only do so much: “The outcome of a state investigation or a private civil suit does not change a deportation order, or any other decision/action by the federal courts or federal immigration authority to prosecute or remove a person from the United States.”

“Every person has the right to live, work, play, and learn safely in Oregon, period,” said Rosenblum when her office released the anti-ICE info.

“I asked my Civil Rights Unit here at the Oregon DOJ to do whatever we could to provide the people, businesses, and local governments of our state with easy-to-read materials to help them know their rights and educate others, and I’m so pleased with what they’ve put together,” she added.

The Beaver State’s top cop said she recommends illegal migrants begin talking with family members to better “understand what protections Oregon’s sanctuary laws provide and what they do not provide, and make a plan for what to do if immigration officials come to your home or place of business.”

“Knowing your rights in advance is essential!” added Rosenblum.

Oregon became the nation’s first sanctuary state in 1987. And in recent years, the state has taken steps to enhance its crackdown on those who violate its sanctuary laws, including with the passage of the Sanctuary Promise Act in 2021 which opened a hotline for residents to report violators.

Trump’s border czar Tom Homan recently The Post that the once and future president may increase the pressure on sanctuary leaders’ efforts to thwart ICE as it works to lock up and deport illegal migrant criminals.

“I’m hoping the president files a lawsuit against them and withholds federal funding,” said Homan.

However, if that doesn’t work, “then we’ll wait til they get out of jail, then we’ll go out into the neighborhoods and get them,” said Homan.

He added: “If they’re not willing to do it then get out of the way — we’re coming.”
