What is the unusual situation in the corruption case against New York City Mayor Eric Adams?

The federal corruption case against Mayor Eric Adams has taken an unprecedented turn as the Department of Justice, now under Trump-aligned leadership, is seeking to dismiss the charges. According to claims, Adams allegedly agreed to enforce President Trump's immigration policies in exchange for having his case dismissed. The judge has ordered Adams' legal team to court to explain this unorthodox sequence of events before deciding whether to dismiss the case. The DOJ wants the dismissal partly so Adams can resume helping President Trump with immigration enforcement initiatives.
