That’s one way to drive up donations before a reporting deadline.

Hillary Clinton’s campaign is stealing from her poorest supporters by purposefully and repeatedly overcharging them after they make what’s supposed to be a one-time small donation through her official campaign website, multiple sources tell the Observer.

The overcharges are occurring so often that the fraud department at one of the nation’s biggest banks receives up to 100 phone calls a day from Clinton’s small donors asking for refunds for unauthorized charges to their bankcards made by Clinton’s campaign. One elderly Clinton donor, who has been a victim of this fraud scheme, has filed a complaint with her state’s attorney general and a representative from the office told her that they had forwarded her case to the Federal Election Commission.
