Why did federal prosecutor Denise Chung resign from her position?

Denise Chung, who headed criminal prosecutors in the D.C. U.S. attorney's office, resigned after being ordered to freeze EPA funds related to environmental grants issued by the Biden administration. She was instructed to issue a freeze order to a bank without proper justification or factual basis - an unprecedented use of the Justice Department's criminal powers. This represents the first instance in the Trump administration where the DOJ has attempted to use its authority without legitimate predicate, essentially suggesting criminal activity where none was proven. The action violated standard DOJ practices as freezing bank assets typically requires evidence connecting those assets to a crime.
