The biggest bank in the United States won't do business with a Missouri conservative group, forcing it to cancel an event next month featuring Donald Trump Jr.

The Defense of Liberty PAC hired WePay, a payment processor owned by JPMorgan Chase, for the Dec. 3 event at the St. Charles Convention Center, the group's founder, former state Rep. Paul Curtman, said Wednesday.

On Nov. 9, the company notified Curtman that it had canceled the contract, refunded the $30,000 already paid for tickets and would not do business with the group in the future.

“It seems you're using WePay Payments for one or more of the activities prohibited by our terms of service," a copy of the message, forwarded to The Independent, states. “More specifically: Per our terms of service, we are unable to process for hate, violence, racial intolerance, terrorism, the financial exploitation of a crime, or items or activities that encourage, promote, facilitate, or instruct others regarding the same."
