Enterprise Rent-a-Car is just one of the many companies who have decided to pull back on their affiliations and partnerships with the National Rifle Association.

Enterprise Holdings is the parent company of Enterprise, Alamo and National, the Washington Post reported. The arrangement, which offered discounts to NRA members, was discontinued Thursday.

“All three of our brands have ended the discount for NRA members,” said a tweet on the Enterprise Rent-A-Car account.

What other companies are severing ties?

The #BoycottNRA movement is spreading rapidly in the wake of last week's deadly high school shooting in Parkland, Florida, with companies like MetLife, Symantec, and SimpliSafe backing off from affiliations with the organization.

CNN on Friday reported that a spokesperson for cybersecurity company Symantec said that the company has "stopped its discount program" with NRA members.

ThinkProgress on Friday reported that SimpliSafe — which has typically offered NRA members two free months of home security monitoring — is also pulling back.

"We have discontinued our existing relationship with the NRA," SimpliSafe spokesperson Cassie Kling wrote, according to the outlet.

First National Bank of Omaha on Thursday also dumped the NRA and revealed that the company will no longer issue the NRA Visa credit card.

According to the bank's Twitter account, customer feedback prompted the decision to opt out of renewing its contract with the NRA.

Customer feedback has caused us to review our relationship with the NRA. As a result, First National Bank of Omaha will not renew its contract with the National Rifle Association to issue the NRA Visa Card.

MetLife on Friday also announced that they would be severing ties with the gun organization.

A tweet from the company's Twitter page read, "We value all our customers but have decided to end our discount program with the NRA."

We value all our customers but have decided to end our discount program with the NRA.

Wyndam Hotel Group on Friday joined the #BoycottNRA movement and announced that they are no longer affiliated with the group.

"Hello. Please know, Wyndham is no longer affiliated with the NRA," the company's Twitter account responded to a consumer inquiry.

Hello. Please know, Wyndham is no longer affiliated with the NRA.

Anything else?

Another trending hashtag emerged on Friday: #StopNRAmazon, which called for the corporation to stop streaming NRA TV.

Deadline reported Friday that Hollywood actors and producers have also supported the social media boycott effort.

Actress Alyssa Milano told Deadline, "The only way to really begin to chip away at the power that the NRA holds over our country, and perhaps even our democracy, is to begin to almost shame companies that are in partnership with the NRA."
