(CNN Money) — A cybersecurity firm. Six car rental brands. A home security company. An Omaha bank. Companies are scrambling to cut ties with the National Rifle Association.

On Thursday, the First National Bank of Omaha pledged to stop issuing an NRA-branded Visa card. A bank spokesperson said “customer feedback” prompted a review of its partnership with the NRA, and it chose not to renew its current contract.

There was a wave of car rental outfits. Enterprise Holdings, which runs the Enterprise, Alamo and National car rental groups, announced that it will end the discount deal it has with the NRA on March 26.

On Friday, car rental company Hertz said in a tweet that it’s also ending its NRA rental car discount program.

The NRA was advertising a Hertz partnership on its “member benefits” page as recently as Friday morning, but that notice disappeared by the afternoon.

Avis and Budget, which are owned by the same company, were also listed as discount providers on NRA’s website Friday. But when reached for comment, Avis Budget Group told CNNMoney that it too was ending its partnership with the organization.

“Effective March 26, our brands will no longer provide the NRA member discount,” an Avis Budget Group spokesperson said via email.

More big names are following suit.

A spokesperson for moving van lines Allied and North American, which are both owned by Sirva, said Friday that the brands “no longer have an affiliate relationship with the NRA effective immediately.”

“We have asked them to remove our listing from their benefits site,” the spokesperson added. The company did not describe what kind of benefits had been offered to NRA members.

Insurance giant MetLife said Friday that it’s ending its discounts on home and auto insurance for NRA members.

Symantec, which makes the Norton anti-virus software and owns the identity theft protection company LifeLock, said Friday that it is severing ties with the NRA. And SimpliSafe, which sells home security systems, said the same.

None of the companies gave details about why or when they decided to cut ties with the NRA, but the news comes as the hashtag #BoycottNRA has circulated widely on social media.

After a mass shooting at a Florida high school last week left 17 people dead, survivors of the massacre have protested for stronger gun laws.

Some of those survivors confronted NRA spokeswoman Dana Loesch at a CNN town hall on Wednesday. Loesch blamed a flawed system for letting people who shouldn’t be able to buy guns slip through the cracks.

Two other companies — the insurer Chubb and Wyndham Hotel Group — confirmed to CNNMoney Friday that they’ve recently ended partnerships with the NRA. However, those decisions were made prior to the shooting at Marjory Stoneman Douglas High School in Parkland, Florida last week.

Chubb said in a statement that it “provided notice of our intent to discontinue participation in the NRA Carry Guard insurance program” three months ago.

The NRA Carry Guard program offers coverage for certain costs associated with gun-related accidents or incidents in which the gun owner claims they lawfully acted in self defense.

Lockton, another insurance firm, continues to underwrite policies for the NRA Carry Guard program, according to the NRA’s website. Lockton did not immediately respond to a request for comment.

Wyndham Hotel Group said in a statement that it “ended our relationship with the NRA late last year.”
