WASHINGTON—JPMorgan Chase has become the target of a campaign by Republican state officials seeking to expose what they see as religious discrimination in the bank’s business practices.
Nineteen Republican state attorneys general sent a letter this month addressed to JPMorgan Chief Executive Jamie Dimon, accusing the nation’s largest bank of a “pattern of discrimination” and of denying customers banking services because of political or religious affiliations. In March, 14 Republican state treasurers wrote a similar letter to Mr. Dimon, making the same accusations.
