Wells Fargo ex-CEO John Stumpf resigns from Chevron, Target boards

Stumpf resigned for personal reasons and not as a result of a disagreement with Chevron, the second largest U.S.-based oil producer said in a regulatory filing on Tuesday. Chevron said on Oct. 3 that it supported Stumpf despite concerns about his leadership at Wells Fargo. Target did not give a reason for Stumpf's resignation.
