Ex-CIA chief issued subpoena in Trump 'grand conspiracy' investigation, lawyer says

WASHINGTON — Former CIA Director John Brennan has been subpoenaed to testify before a Florida grand jury in a Justice Department investigation into whether former law enforcement and intelligence officials conspired against President Donald Trump, and is the target of a separate inquiry into whether he made false statements before Congress, one of his lawyers said Monday.

Ken Wainstein, an attorney for Brennan, disclosed the existence of the subpoena as he argued for a court order requiring the Justice Department to preserve all records from the investigations. He said those documents would be a "fertile source" of information about the government's determination to indict Brennan, an outspoken Trump critic, and would be needed for the defense to challenge any potential prosecution of the ex-CIA chief as unconstitutionally vindictive and selective.
