Wasn't Timothy McVeigh affiliated with the Michigan Militia? Maybe not a member, but an attendee at a few meetings?
In this case, it sounds like the Michigan Militia are denouncing this group, and refused them refuge during the first night of raids. So good on them!
If memory serves, McVeigh attended a few meetings but was ousted due to his advocacy of violence. After the Oklahoma City bombing, the FBI tried to link McVeigh with the Michigan Militia, but eventually dropped the accusation.
Found this online from Wikipedia: Timothy McVeigh was erroneously associated with the Militia by the mainstream media, but the Michigan Militia was later declared by the FBI to be clear of involvement with McVeigh and the Oklahoma City bombing.
