Federal prosecutors in Chicago face potential criminal contempt charges. U.S. District Judge April Perry found serious grand jury misconduct in a case stemming from President Donald Trump's immigration crackdown, according to court records. Defense attorneys requested an independent special prosecutor with authority to bring contempt charges, but the Justice Department opposed the move, arguing it would "amount to criminal proceedings against federal prosecutors," WTTW reported. Former Assistant U.S. Attorney Sheri Mecklenburg required three grand jury sessions to secure an indictment after initial juries refused. The Justice Department is reviewing potentially 1,000 grand jury transcripts for similar problems and auditing Mecklenburg's work since 2007.
