Bill Zito has replaced Darin Gardner, who left the office one month after replacing Steve Ruhlen. Ruhlen, in turn, also left after a several-week stint from July to August. Overall, Granger has had three chiefs of staff since July and five since the start of 2015. Matt Leffingwell had served as her chief of staff since 2012 but departed in January of this year. His position was filled by Shannon Meade who stayed until July when she was replaced by Ruhlen.
Bill Zito joins Granger after serving for two years as the deputy chief of staff for Rep. John Carter (R-Texas) since late 2013. He began his Hill career as an U.S. Army congressional fellow in 2012.
