Twitter accounts for the three brands tweeted the statement in response to inquiries from users, some of whom identified themselves as customers, demanding it sever ties with the NRA.

The decision followed one by the nation’s largest privately-owned bank holding company, Nebraska-based First National Bank of Omaha, to stop producing credit cards for the NRA.
