Sheriff Christina Corpus is requesting the recusal of District Attorney Steve Wagstaffe from any prosecutorial role and administration of civil grand jury proceedings regarding the sheriff, according to a claim filed with the courts Monday. On May 28, Wagstaffe subpoenaed Corpus — who may be the first sheriff removed from office in California’s history over allegations of misconduct — to appear for the civil grand jury to “testify as a witness in a pending investigation” on June 10.
