What was the purpose of the open letter from former prosecutors to current federal prosecutors?

The open letter was signed by former Justice Department lawyers to show support for current prosecutors who are being pressured while trying to do the right thing. The letter specifically addresses concerns about the Eric Adams case, where prosecutors were reportedly forced to dismiss charges against the New York City Mayor. Former U.S. Attorney Barbara McQuade explained that the letter's signatories were appalled by these events and wanted to stand in solidarity with prosecutors nationwide who might face similar pressure to compromise their integrity.
