ATLANTA— Atlanta Hawks co-owner Bruce Levenson said Sunday he is selling his controlling interest in the team, in part due to an inflammatory email he said he wrote in an attempt "to bridge Atlanta's racial sports divide." Levenson said he regrets the email sent to the team's co-owners and general manager Danny Ferry two years ago as "inappropriate and offensive." In a statement released by the team, Levenson said he sent the email due to his concerns about low attendance and a need to attract suburban whites.
