Jury selection begins Monday in the trial of the alleged ringleader of a scheme to exploit the COVID-19 pandemic that federal prosecutors say stole $250 million from a program meant to feed children, the latest chapter in a broader case that has also included an attempt to bribe a juror and political repercussions against Gov. Tim Walz.

But the attorney for Aimee Bock, the founder of Feeding our Future — the group that prosecutors say was at the heart of the plot — insists that she’s innocent.

Bock and a co-defendant will be the second group to stand trial in what prosecutors call one of the country’s largest COVID-19-related fraud cases anywhere. The first trial resulted in the conviction of five people last year and received widespread attention after some defendants and people linked with them allegedly tried — unsuccessfully — to bribe a juror with a bag of $120,000 in cash. The juror went straight to police instead.
