What extraordinary action did the Department of Justice take regarding Mayor Eric Adams and how did it impact the prosecution team?

Last week, the Department of Justice issued an extraordinary memo mandating that charges against NYC Mayor Eric Adams be dropped. This unusual intervention prompted a Trump-appointed Southern District prosecutor to resign in protest, despite not being an ally of Adams, because she felt the situation represented an unjust quid pro quo arrangement. The prosecutor's resignation is particularly notable as she was described as not being a 'resistance person' or politically opposed to the administration, suggesting her ethical concerns about the DOJ's directive transcended political affiliations. She considered the intervention so unjust that she could not continue in her position.
