Subpoena is among a flurry issued in recent weeks as part of DoJ inquiry into alleged conspiracy against Trump

The former CIA director John Brennan has been subpoenaed to testify next month before a Florida grand jury as part of a Department of Justice investigation into whether former law enforcement and intelligence officials conspired against Donald Trump, one of his lawyers said Monday.

Ken Wainstein, an attorney for Brennan, disclosed in a court filing that prosecutors last Thursday presented him with a subpoena for Brennan to appear before a grand jury in Fort Pierce, Florida, on 15 October.
