The Justice Department on Monday ordered federal prosecutors to drop corruption charges against New York City Mayor Eric Adams, arguing in a remarkable departure from long-standing norms that the case was interfering with the mayor’s ability to aid the president’s crackdown on illegal immigration.

In a two-page memo obtained by The Associated Press, acting Deputy Attorney General Emil Bove told prosecutors in New York that they were “directed to dismiss” the bribery charges against Adams immediately.

Bove said the order was not based on the strength of evidence in the case, but rather because it had been brought too close to Adams reelection campaign and was distracting from the mayor’s efforts to assist in the Trump administration’s law-and-order priorities.
