SOUTHFIELD, Michigan (CNN) - Less than a year after he was released on parole from a Michigan prison for second-degree murder, assisted suicide advocate Jack Kevorkian announced Monday he is running for U.S. Congress.
Kevorkian, 79, will challenge Rep. Joe Knollenberg, a Republican who has represented Michigan's 9th District since 1993.
At a lengthy news conference in suburban Detroit, Michigan, Kevorkian - who is still on parole - voiced his strong opposition to the war in Iraq.
"I am justified in saying that the United states is a criminal nation. We're a bull in the china shop," he said. "We have committed a horrendous international crime."
He also said he would push for legalizing marijuana in some instances, but was vague on whether his support of assisted suicide would be a campaign issue.
Kevorkian was released on parole on June 1 after serving more than eight years of a 10- to 25-year sentence at Lakeford Correctional Facility, a maximum-security prison in Jackson, Michigan.
He was convicted of second-degree murder in the 1998 death of Thomas Youk, 52, of Waterford Township, Michigan. Youk suffered from amyotrophic lateral sclerosis, or ALS, commonly known as Lou Gehrig's disease.
