"They just have to come from some place [outside Wells] and they shouldn't come from Wall Street," the billionaire Berkshire Hathaway Inc. chairman told the Financial Times in an interview published Sunday.
Hiring the bank's next leader from Wall Street is "just not smart" because that's "automatically going to draw the ire of a significant percentage of the Senate and the U.S. House of Representatives," he said.
The new Wells CEO "probably shouldn't come from JPMorgan or Goldman Sachs," Mr. Buffett added.
Mr. Buffett said Wells Fargo's competitive position remains strong, despite damage done by the scandal, according to the newspaper.
"One household out of every three does business with Wells one way or another," he said.
