Major partners in Facebook Inc.’s Libra cryptocurrency group including Visa Inc. and Mastercard Inc. are considering withdrawing their support, according to an unconfirmed report published today.

The Wall Street Journal reported that the two main credit card providers along with “other financial partners” were reconsidering their involvement because of the backlash against the proposed cryptocurrency by U.S. and European government officials. None of the partners has yet pulled its support, but a number have declined requests from Facebook to support Libra public, according to the report.

The Journal report isn’t the first time it has been suggested that major backers of Libra are looking to pull the pin. The Financial Times reported in August that “at least three [are] privately discussing how to distance themselves from the venture.” Two of the founding backers told FT that they were considering cutting support on concerns about the regulatory spotlight, while a third said it was worried that supporting Libra could result in unwanted attention from agencies that oversee their business.

FT didn’t name any of the companies, but Visa and Mastercard, per the Journal report, are the most obvious ones. Other financial partners that could be thinking of pulling support include PayPal Holdings Inc., Stripe Inc. and PayU. Partners such as eBay Inc., Booking Holdings Inc., Lyft Inc. and Uber Technologies Inc. are primarily recipients of Libra payments and might not face as much scrutiny.

There’s an outside chance that the list may include some of the blockchain companies such as Coinbase Inc., Xapo Inc., Bison Trails and Anchorage, since they too could be concerned about regulatory review.

Libra launched in June and it took all of a single day for the proposed cryptocurrency to be criticized. Starting with members of Congress and later U.S. President Donald Trump, a Senate hearing that started July 16 turned into a farce when a congressman compared Libra to the 9/11 terrorist attacks.

Across the Atlantic, the rhetoric has been a little less insane but still strong. Bruno Le Maire, France’s minister of the economy and finance, called for an European Union-wide ban on Libra Sept. 12, while there have been numerous investigations and hearings into the cryptocurrency as well.
