When the chair of Wells Fargo, Elizabeth A. Duke, appears before the House Financial Services Committee next week, Representative Maxine Waters will have a simple message for her: Resign.

A day after Ms. Waters’s committee released details of an investigation of Wells Fargo, she said Ms. Duke and another board member, James Quigley — who sought a light touch from a political appointee at the federal consumer protection agency — should step down.

“Both of them had a clear dereliction of duty as board members,” Ms. Waters, a California Democrat and the chairwoman of the Financial Services Committee, said on a call with reporters.

A Wells Fargo spokeswoman declined to comment.

The committee looked into Wells Fargo’s interactions with regulators over a series of misdeeds the bank had disclosed since 2016, including that it spent years opening fake accounts in customers’ names, forcing them to buy unnecessary auto insurance and charging them inappropriate mortgage fees.
