Grand jury subpoenas broaden Brennan probe under new DOJ leadership

Witnesses cooperating with the Justice Department's criminal probe into former CIA Director John Brennan were subpoenaed to testify before a Washington, D.C. grand jury after Joe DiGenova was appointed to oversee the case, with many having already been interviewed by investigators; the inquiry centers on Brennan's congressional testimony about the CIA's role in the Steele dossier and related matters.
