A Colorado man suspected of making racist threats against Barack Obama is scheduled to appear in federal court Thursday on a charge of methamphetamine possession. Therin Gartrell, 28, was also scheduled to be charged with state violations Thursday, but that was put on hold without explanation. Gartrell was arrested in suburban Aurora last weekend, days before the Democratic national convention. Authorities say they found scoped rifles, a bulletproof vest, wigs and fake IDs in a rented truck he was driving. Authorities say Gartrell and two other men talked about killing Obama. The US attorney's office later said the men were drug users making racists threats, and that they had no firm assassination plot and no ability to carry one out.
