Gov. Ernie Fletcher has been subpoenaed to appear before the special grand jury investigating personnel practices within his administration.
The attorney general's office has confirmed the subpoena.
Fletcher has been summoned to appear on August 30.
Spokeswoman Vicki Glass declined to say if Fletcher must also produce documents along with his appearance.
In previous statements, Fletcher declined to say if he would answer questions before the panel or invoke his Fifth Amendment right against self-incrimination.
The special grand jury has previously summoned virtually all of Fletcher's top staff.
Fletcher has been sharply critical of the special grand jury investigation being operated by the office of Democratic Attorney General Greg Stumbo.
Fletcher's office declined to comment on the subpoena.
