Forrest Covington refers to his Mentally Ill Brother

From the News & Observer (Raleigh), 23 January 2000:

I also have a family member, an elder brother, who suffers from schizophrenia, so I am very sympathetic to the plight of the mentally ill. - Forrest Covington

Cf. Benjamin Covington in a 2008 interview:

They put Harold on restrictive duty, and they ordered him to see the base psychiatrist to be evaluated as to whether or not he was medically fit to be in the military. Ultimately, he was in fact diagnosed as having paranoid personality disorder.

My parents were really upset about the whole white supremacist thing. What the Army psychiatrist told my parents — and what my parents repeated to us off and on over the years — was that it could have been anything. He could have been a Jesus freak, he could have been a Hare Krishna, he could have been anything — anything that the mental illness could latch onto. And it happened that he latched onto the neo-Nazi, white supremacist ideology. He was determined to be medically unfit, and he was discharged from the Army in 1972.
