No one denied that Sholom Rubashkin’s crimes were serious. The former chief executive of what was once the country’s largest kosher meatpacking plant was convicted of more than 80 counts of financial fraud in 2009, following a massive immigration raid on the family-owned facility in northeastern Iowa. Prosecutors said he had profited off the labor of undocumented immigrants, some of them children, and had bilked lenders out of more than $26 million.

But his punishment was draconian, some argued, especially for a first-time, nonviolent offender. Though Rubashkin was cleared of immigration and child labor violations, a federal judge sentenced him to 27 years in prison, longer than some defendants receive for murder. For the middle-aged father of 10, it amounted to a de facto life term.

On top of that, an array of lawmakers, law enforcement officials and legal experts claimed his case had been tainted by egregious misconduct by prosecutors. His supporters included five former attorneys general, including Michael Mukasey, who headed the Department of Justice when Rubashkin was charged. As Rubashkin idled in a New York correctional facility, calls mounted for his sentence to be commuted.

The Obama administration rebuffed the efforts. But on Wednesday, President Donald Trump commuted Rubashkin’s sentence, in his first use of the presidential power.

The White House said in a statement that Trump made the decision at the urging of law enforcement officials, legal experts and congressional leaders from both sides of the aisle, including House Minority Leader Nancy Pelosi, D-Calif., and Sen. Orrin Hatch, R-Utah. The statement offered few details, but noted that the action was not a presidential pardon vacating his conviction. “The President’s review of Mr. Rubashkin’s case and commutation decision were based on expressions of support from Members of Congress and a broad cross-section of the legal community.”

Rubashkin, before he was imprisoned, and members of the Rubashkin family then and since, have been significant contributors to political candidates and committees, most but not all of them Republicans, according to the database kept by OpenSecrets.org.

Rubashkin, now 57, had served more than eight years in prison. He was released on Wednesday from the Federal Correctional Institution in Otisville, N.Y., where his wife picked him up, according to the Des Moines Register. His attorney, Guy Cook, praised the president’s move, saying his longtime client “has finally received justice,” the newspaper reported.

“President Trump has done what is right and just,” Cook told the Register. “The unrelenting efforts on behalf of Rubashkin have finally paid off.”

But Robert Teig, a former U.S. attorney in Iowa who was involved in Rubashkin’s prosecution, told the Associated Press that the commutation “makes no sense” given Trump’s vows to crack down on illegal immigration. In comments to the Register, he added: “[Rubashkin] couldn’t win legally, factually or morally, so he had to win politically. It’s sad when politics interferes with the justice system.”

The case against Rubashkin unfolded in May 2008, when a small army of helicopters, buses and federal agents in tactical gear descended on the Agriprocessors slaughterhouse in Postville, Iowa, which was suspected of employing undocumented immigrants. Never before had so many law enforcement officers raided a single business site, it was reported at the time.

Authorities rounded up 389 undocumented immigrants, more than 20 of them minors, who described a long list of abhorrent working conditions, including 12-hour shifts without overtime pay and exposure to dangerous chemicals. A spokesman for a food workers union compared it to scenes from Upton Sinclair’s “The Jungle.”

Some female employees also alleged they were sexually coerced by managers, the Star Tribune and others reported in 2008.

An informant’s tips led to the raid. The informant witnessed plant managers hire and help workers with fake identity papers, and reported seeing managers abuse workers, including hitting one with a meat hook. One manager also ran a scam in which illegal workers were coerced into buying cars from him, according to a search warrant filed before the raid.

After the raid, workers told investigators that they were routinely put to work without safety training and were forced to work long shifts without overtime, the New York Times reported. Underage workers said their bosses knew how young they were.

Rubashkin and other company executives faced a range of charges, including conspiracy to harbor undocumented immigrants for profit and more than 9,000 child labor law violations. He was accused of helping workers obtain fraudulent ID cards and paying in cash under the table, among other offenses.

Eventually, prosecutors zeroed in on financial crimes, alleging Rubashkin laundered money through a secret bank account and submitted fake documents to banks so he could borrow more. He was acquitted of the child labor claims but convicted on 86 counts of federal bank fraud and money laundering. The immigration charges were dismissed. His appeal was rejected by the U.S. Supreme Court.

Prosecutors initially sought a life sentence, then changed their request to 25 years in prison. When U.S. District Judge Linda R. Reade sentenced him to 27 years, many observers noted that it was nearly three years longer than the term former Enron chief executive Jeffrey Skilling received for his collapse of the energy giant.

Why Reade imposed such a severe sentence has long been disputed. But a group of more than 107 former DOJ officials said in a letter to the Obama administration in 2016 that prosecutors had improperly interfered with the sale of Agriprocessors, which filed for bankruptcy shortly after the immigration raid.

According to the officials, prosecutors drove away prospective buyers, including one who offered $40 million for the company. The apparent goal was to make sure that none of Rubashkin’s family members could take over.

When Agriprocessor was eventually sold for $8.5 million, the company’s lenders were left with huge losses, making Rubashkin’s crimes seem far more severe than they actually were, the officials said. The U.S. attorney’s office in northern Iowa has rejected the allegations.

“Experienced former prosecutors and career Justice Department officials view this case as a stain on an institution created to uphold the law,” Philip B. Heymann, a former deputy attorney general under President Bill Clinton, wrote in a Washington Post op-ed late last year. “If the department’s leadership refuses to act, I hope President Obama pardons Rubashkin and ends this tragedy. The alternative is a display of either blind self-righteousness or frightened defensiveness that is inconsistent with the Justice Department we all have served and respected.”
