Earlier this morning it was reported that Morgan Stanley "reviewed its visitor logs" upon hearing that one of its employees was supposedly conducting business with Anna Gristina/Scotland, a purveyor of prostitutes, when she was arrested this week. In the event the bank is still on the hunt, Charlie Gasparino claims to have a name. "...the executive involved with UES madam has been identified as David Walker, a broker in the midtown office. He has not been charged and didn’t return calls. Morgan Stanley has no comment." Not to be confused with this guy.
