In a two-page memo released Monday, Sessions said agreements reached previously between the department’s civil rights division and local police departments — a key legacy of the Obama administration — will be subject to review by his two top deputies, throwing into question whether all of the agreements will stay in place.

The memo was released not long before the department’s civil rights lawyers asked a federal judge to postpone until at least the end of June a hearing on a sweeping police reform agreement, known as a consent decree, with the Baltimore Police Department that was announced just days before President Trump took office.

“The Attorney General and the new leadership in the Department are actively developing strategies to support the thousands of law enforcement agencies across the country that seek to prevent crime and protect the public,” Justice officials said in their filing. “The Department is working to ensure that those initiatives effectively dovetail with robust enforcement of federal laws designed to preserve and protect civil rights.”
