Why did Denise Chung resign from the U.S. attorney's office?

Denise Chung resigned from the U.S. attorney's office in Washington, D.C. due to a constitutional concern. She was asked by the Deputy Attorney General to freeze assets without sufficient evidence, which she viewed as a violation of constitutional prohibitions. Rather than comply with an order she believed was unlawful, she chose to uphold her oath to the Constitution by refusing and resigning. Former prosecutor Andrew Weissmann describes this as an extremely serious situation, calling it not just a warning sign but evidence of "lawless action" being ordered within the Justice Department. He frames her resignation as part of a broader pattern of constitutionally questionable demands being made of federal prosecutors who have taken oaths to uphold the law.
