WASHINGTON (AP) — Randal Quarles, who is vice chairman for supervision at the Federal Reserve, says he will recuse himself from participating in matters specific to Wells Fargo & Co. The Fed announced the decision on Friday, saying Quarles wanted to "avoid even the potential appearance of a conflict of interest." Quarles noted that he had severed all financial ties he and his immediate family had with the bank, including selling off his stock in the banking giant.
