n a motion filed last month, O'Mara claimed Lester made "gratuitous" and "disparaging remarks" about Zimmerman and showed bias in a July 5 ruling that raised Zimmerman's bond from $150,000 to $1 million.

The bond increase came after prosecutors presented evidence Zimmerman and his wife, Shellie, misled the judge about their finances. Shellie Zimmerman was later charged with perjury.
