The case began to unfold four years ago after a Yorkville bank noticed the suspicious withdrawals. After he was told by bank officials that any withdrawals of $10,000 or more had to be reported to regulators, Hastert began to withdraw cash in $9,000 increments. In all, he took out $1.7 million over 4½ years, paying Individual A in increments of up to $100,000 in meetings at a Yorkville restaurant parking lot, prosecutors said.
