Big law firms are, for the most part, conservative institutions that often represent a wide range of clients with varying business interests, many of whom tend to shy away from controversy, regardless of their politics. Mr. Giuliani’s connection to Mr. Trump, his unpredictability and his recent history of outbursts in his frequent television appearances could make him a challenging client.
