U.S. Attorney orders review of over 1,000 grand jury cases after Broadview Six scandal
More than a thousand grand jury presentations are now under scrutiny after federal prosecutors in Chicago were compelled to drop charges in the so-called "Broadview Six" case, following revelations of grand jury abuse and prosecutorial misconduct, the district’s top federal prosecutor confirmed Wednesday.
Speaking on the sidelines of an unrelated press conference in Washington, D.C., U.S. Attorney Andrew Boutros for the Northern District of Illinois said his office is conducting a sweeping review of prosecutorial conduct in cases stretching back nearly two decades, as part of an effort to restore public faith in the grand jury system.
“When this is all said and done, I will tell you that well over 1,000 grand jury presentations will be reviewed in the Northern District of Illinois,” Boutros told reporters.
“They will both be retroactive, looking at what happened in some cases going all the way back almost 20 years. It will cover everything that is happening now that’s pending in court.”
Many of the federal cases now under review resulted in lengthy prison sentences — some lasting decades — which could open the door to potential exonerations and habeas petitions if similar misconduct is uncovered.
Boutros said the review of active cases is designed to reassure judges and the public that the same problems that plagued the Broadview Six case are not recurring. The case involved a group of protesters arrested last fall outside a U.S. Immigration and Customs Enforcement facility in Broadview, Illinois.
The prosecutor has faced mounting pressure in recent months as details of misconduct emerged. The case collapsed after U.S. District Judge April Perry took the unusual step of unsealing secret grand jury transcripts, which revealed that prosecutors had acted improperly while seeking an indictment against the protesters.
At the center of the controversy is former Assistant U.S. Attorney Sheri Mecklenburg, who left the office to work for Senator Dick Durbin, an Illinois Democrat. The transcripts showed Mecklenburg improperly “vouched” for the strength of the government’s evidence, dismissed grand jurors who disagreed with the allegations, and contacted a grand juror outside formal proceedings.
Durbin subsequently fired her from her post.
In response to the revelations, Boutros announced a remediation plan that includes new internal guidelines — what he described as “very bright lines” — around when prosecutors must disclose grand jury material and under what circumstances.
The second component of the plan is a sweeping review of past cases, not only those handled by Mecklenburg but also other prosecutors in the office, Boutros said.
“It’s going to be a massive review, a comprehensive review, and it is underway,” he said.
In a court filing last week, Boutros moved to dismiss charges against four men in a 2018 arson case, citing Mecklenburg’s comments to grand jurors in 2025, including “we can prove this case,” “we don’t catch the smart ones,” and “most of them aren’t as smart as they think.”
Legal analysts say the scandal has dealt a serious blow to the credibility of the U.S. Attorney’s Office in Chicago. CBS News Chicago legal analyst Irv Miller, who has both represented clients in cases involving Mecklenburg and worked with her on outside projects, said reestablishing trust with federal judges is now the office’s top priority.
“I’ve never seen it happen before and the U.S. Attorney knows it was a major, major mistake, and is trying to correct it right now,” Miller said. “The question is, can it be corrected?”
So far, charges have been dropped against ten defendants in three separate cases. It remains unclear how many additional cases could be dismissed as the review continues.
CBS News Chicago reached out to Mecklenburg through her attorney but was told she has no comment.
