In New Jersey, Mercer County officials have enacted new policies limiting the ability of federal immigration agents to access and use county property to conduct immigration enforcement operations.

Mercer County Executive Dan Benson issued an executive order and the Board of County Commissioners passed a resolution Friday that bans U.S. Immigration and Customs Enforcement and Customs and Border Patrol from using any nonpublic area on county property to enforce immigration law, unless they have obtained a judicial warrant or judicial order.

“From Minneapolis to Delaney Hall, ICE has repeatedly shown a total disregard for the law and for the constitutional rights of citizens and non-citizens alike,” Benson said in a statement. “We respect the Federal Government’s authority to enforce immigration law, but we will not allow them to use County properties to harass our families.”

Amtrak said it didn’t expect to lift its suspension until at least noon.

Travel Advisory: Due to unforeseen track and signal maintenance resulting from a now extinguished fire in the New York area, all services traveling south of New York (NYP) are temporarily suspended. This suspension is anticipated to be in place until noon at a minimum. Services…

Video from outside Penn Station showed smoke billowing in the pre-dawn hours, as emergency personnel stood by with stretchers awaiting any potential victims.
