Growing list of companies are cutting ties with NRA

A growing number of companies are announcing plans to sever ties with the National Rifle Association following the shooting massacre Feb. 14 at Marjory Stoneman Douglas High School in South Florida that killed 17 students and staff, sparking renewed calls for gun control.

One of the first companies that said it would cut ties with the gun-rights lobbying group was First National Bank of Omaha, which announced Thursday that it would not renew a co-branded Visa credit card with the NRA.

A slew of other companies -- including United Airlines, MetLife Inc., Hertz and Best Western -- have followed suit, announcing plans to terminate special discounts and benefits for NRA members.

And as petitions circulate online urging companies to #BoycottNRA, the pressure to disassociate from the NRA is growing. #BoycottNRA has already trended on Twitter.

The NRA slammed companies who have been cutting ties with the group, calling it a "shameful" move.

"The law-abiding members of the NRA had nothing at all to do with the failure of that school’s security preparedness, the failure of America’s mental health system, the failure of the National Instant Check System or the cruel failures of both federal and local law enforcement," the NRA said in a statement Saturday. "Despite that, some corporations have decided to punish NRA membership in a shameful display of political and civic cowardice."

The NRA added the "loss of a discount will neither scare nor distract one single NRA member from our mission to stand and defend ... individual freedoms."

Below, the companies distancing themselves from the NRA:
