LONDON -- Visa says it has suspended all payments to WikiLeaks pending an investigation of the organization's business.
Visa's decision is a powerful blow to the loosely knit organization, which relies on online donations to fund its operations.
Popular online payment company PayPal, Inc. has already severed its links with WikiLeaks. Visa's decision to pull the plug on WikiLeaks leaves the website with one fewer source of revenue.
Swiss authorities closed Assange's new Swiss bank account Monday.
