The former leader of a Minnesota nonprofit who was convicted for her role in a staggering $250 million fraud case that helped ignite a federal immigration crackdown should spend 50 years in prison, prosecutors argued in a court filing.

Aimee Bock, who ran the organization Feeding Our Future, which claimed it helped provide millions of meals to children in need during the pandemic, is set to be sentenced Thursday in federal court in Minneapolis. President Donald Trump used the fraud cases to initially justify a massive surge of federal officers to the Minneapolis-St. Paul area last winter, leading to a pushback by residents and the deaths of two people.

"Feeding Our Future operated like a cash pipeline, open to anyone willing to submit fraudulent claims and pay kickbacks," prosecutors said in the Monday filing. "The ripple effects of her actions are profound, immeasurable, and will have lasting consequences for both Minnesota and the nation."

Bock was convicted last year of multiple counts involving conspiracy, wire fraud and bribery. She has long insisted she is innocent.

Her lawyer, Kenneth Udoibok, argued in a separate filing that she shouldn't have to serve for more than 37 months in prison, saying she had provided information to investigators. He argued that Bock had been unfairly painted as the mastermind and insisted that two co-defendants were responsible for running the scams.

The nonprofit sat atop a fraud network that included a web of partner organizations, phony distribution sites, kickbacks and fake lists of children supposedly being fed, prosecutors say. Dozens of people, many from the state's large Somali community, have been convicted for their roles in a series of overlapping food fraud cases that have spent years in the courts.

Trump, who has long derided Somalis, last year blasted the state as "a hub of fraudulent money laundering activity." He also criticized the leadership of Gov. Tim Walz, the Democrats' vice presidential nominee in the 2024 election.

"Somali gangs are terrorizing the people of that great State, and BILLIONS of Dollars are missing. Send them back to where they came from," Trump wrote on social media.

Bock is white and the U.S. Attorney's Office says the overwhelming majority of defendants in the cases are of Somali descent. Most are U.S. citizens.

The immigration surge led to repeated protests and confrontations between residents and federal officers and resulted in the killings of Renee Good and Alex Pretti.
