In what is sure to go down as one of the ugliest law firm breakups in South Florida, personal injury attorney John Leighton is suing his former longtime partner and boss, Ira Leesfield, and asking for a court order to see the firm’s financial records.

Among the explosive charges, Leighton claims Leesfield used law firm funds for Hillary Clinton’s presidential campaign while serving as her Florida finance co-chair and being away from the firm for several months in 2007 and 2008.
