Feeding Our Future’s former executive director Aimee Bock testified that she helped identify and stop fraud. She’s accused of leading a $250 million fraud scheme.

The leader of Feeding Our Future denied taking kickbacks from meal providers who defrauded the federal government, describing herself Wednesday as a tough watchdog of taxpayer funds who booted dozens of sites from her organization and reported any fraud concerns to state regulators.

Prosecutors showed the jury a breakdown earlier in the trial alleging Bock received $1.9 million in total food program money.
