Why did federal prosecutor Denise Chung resign from the Trump Administration's Justice Department?

Denise Chung resigned after refusing to lie about an investigation and put that lie in writing. She believed the Trump Justice Department was asking her to participate in what she viewed as an illegal seizure of banking records, and she took a principled stand against this unethical request. Chung, a 1995 Harvard Law School graduate, had served as a prosecutor in the Justice Department for 24 years, beginning under Republican President George W. Bush and continuing through subsequent administrations until her resignation. Her departure represents a significant protest against what she perceived as improper political pressure compromising legal ethics.
