And the architect of New Jersey's sanctuary policy for immigrants is asking a federal judge to toss a Trump administration lawsuit that targets Newark, Hoboken, Jersey City and Patterson for their local immigration policies.

Former Attorney General, Gurbir Grewal, who's representing Newark and Hoboken in the case, filed a letter to the courts on Thursday, arguing the suit has no legal standing and violates the 10th Amendment, which bars the federal government from forcing states to carry out national immigration laws.

In the letter, Grewal argues Newark and Hoboken are aligned with New Jersey's 2018 statewide directive, which details how and when local police can assist federal immigration agents.

The Trump administration sued the cities in May claiming the local rules interfere with federal law, but Grewal letter points to multiple court rulings, including one from 2020 that rejected similar claims.

Grewal to quickly dismiss the case, saying it is critical to protect public safety.
