A Mississippi congressman on Tuesday asked the FBI to review the slaying of an openly gay mayoral candidate to determine if any federal laws might have been violated.

U.S. Rep. Bennie Thompson's district includes Clarksdale, where Marco McMillian was running. McMillian, 34, was found slain last week in a rural area nearby.

Thompson, a Democrat, said Tuesday that he has confidence in the sheriff investigating the death but that he wants the FBI to get involved because that's what McMillian's family wants.

"If another set of eyes looking at it would provide additional information, I think it would be helpful to the McMillian family," Thompson told The Associated Press in a phone interview.

An FBI spokeswoman didn't immediately respond to an emailed request for comment after hours.

McMillian's campaign had said he was one of the first openly gay, viable candidates for public office in Mississippi.
