Believe it or not, but I know Sholom personally and many of his ill doings. I also know everyone else that was convicted in this case. (HR manager, accountant).
He was convicted for fraud, because it was an easy case. He was never tried for labor violations, but he was guilty as hell. Postville, Iowa (population 2500 at the time) was home to the largest immigration raid in US history. They all worked at AgriProcessors. His workforce was knowingly built on illegals. They were recruited from Mexico and brought up. It was absolutely freaking crazy. There were 13 year old Guatemalans working on the killing floor.
Trump commuting Sholom’s sentence shows me he really doesn’t give a crap about illegal immigration, other than as a way to rile up his base. Sholom is the most egregious example of an individual profiteering from mass illegal immigration that I can think of. He straight up recruited and brought in illegals, paid them peanuts (even kids), fabricatied documents, and made a killing.
