A Chevron board member has resigned weeks after the oil major said the businessman had its full support in the wake of a customer service scandal.
John Stumpf also stepped down from the boards of Wells Fargo and Target Corp this month.
He is reported to have resigned for personal reasons and not as a result of a disagreement with Chevron, according to a company filing.
Chevron had previously said it supported Stumpf despite concerns about his leadership at Wells Fargo.
He joined the board six years ago.
The move by Stumpf came amid revelations the bank had for years opened checking, savings and credit card accounts without customer approval to satisfy managers’ demand for new business.
Stumpf had resigned from an advisory role at the US Federal Reserve earlier this month.
