FedEx on Tuesday doubled down on its decision to continue to offer discounts to members of the National Rifle Association.

FedEx said in a statement to Business Insider that "the NRA uses UPS and not FedEx " for shipping from its online store.

More than a dozen companies — including Hertz, United, and Delta — have recently cut ties with the NRA.

FedEx is doubling down on its ties to the National Rifle Association — and trying to shift the focus to one of its biggest rivals, UPS.

FedEx told Business Insider on Tuesday that "the NRA uses UPS and not FedEx " for shipping from its online store.

The UPS jab was part of a statement from FedEx intending to "provide important, clarifying facts." The NRA's online store confirms that it uses both the US Postal Service and UPS to ship products.

"First, the pricing program that is the focus of these concerns is not for the NRA itself — it is for American small businesses and consumers that are members of the association," the latest FedEx statement says.

Last week, in the wake of a shooting at a Florida high school that left 17 people dead, people on social media began to pressure companies that offer special deals to NRA members to cut ties with the group. More than a dozen — including Hertz, United, and Delta — have recently done so.

"FedEx has never provided any donation or sponsorship to the NRA, which is one of hundreds of alliance and association participants that serve more than one million customers," the company said in a statement on Tuesday. "FedEx remains committed to all our customers and the pricing we provide them independent of their political affiliations and views."

As FedEx has stayed loyal to the NRA, the boycott pressure has increased, with people saying they'll use UPS rather than FedEx to ship items. The pop-punk band Blink-182 and the ice cream brand Jeni's Splendid Ice Cream were among the people and groups saying on Monday that they would no longer use FedEx.
