Major companies such as United, Delta, Enterprise Holdings, First National Bank of Omaha, Symantec and MetLife were among the first to call it quits after a #BoycottNRA hashtag started to pick up steam online last week.

The NRA was initially mum on the tragic event but later went on the offensive during an annual gathering of conservatives at the Conservative Political Action Conference (CPAC) outside Washington last Thursday, igniting the boycott.

The gun rights group’s chief executive Wayne LaPierre openly criticized gun-control advocates and the media for its coverage of the shooting.

“They don’t care about our schoolchildren,” LaPierre said Thursday. “They want to make all of us less free,” adding that Democrats are pushing a “socialist” agenda to deprive gun owners of their weapons.

“Socialism is a movement that loves a smear," he added.

Those comments, however, did not sit well with people who later took to Twitter urging companies to halt partnerships with the organization. Since Thursday, close to a dozen companies have announced its ending deals with the gun’s group.

The NRA later fired back with a tweet saying: “Let it be absolutely clear. The loss of a discount will neither scare nor distract one single NRA member from our mission to stand and defend the individual freedoms that have always made American the greatest nation in the world.”

Here are the companies that have promptly responded to customers and severed their relationships with NRA.
