JOHN DAY, Ore. (AP) — An Oregon sheriff repeatedly invoked his right against self-incrimination while being questioned under oath about his email practices.

Grant County Sheriff Glenn Palmer was questioned twice last week by an attorney representing The Oregonian/OregonLive, which sued the sheriff in an effort to obtain public records.

The news organization reports Palmer answered questions during the deposition about his knowledge of state law governing public records, his handling of requests for records and his cellphone use.

Questions about his personal email account prompted the Fifth Amendment claims and he declined a follow up request for comment.

Palmer gained notice earlier this year when he met with those who occupied the Malheur National Wildlife Refuge. He considers himself a “constitutional sheriff” and vows to protect citizens from abusive government.
