Bill Singer talks with Brittany Weiner, attorney with Imbesi Law, about former Wells Fargo broker Donna Sabb, and a family feud that spilled over into FINRA arbitration; Sabb, who was sued by her nieces and a nephew over "misappropriation" in accounts that Sabb established and funded, was found innocent by FINRA arbitrators. Now Weiner is seeking an expungement of the complaint from her records.—Tyler Sill
