Tharin Gartrell is due in Arapaho County Court on Thursday.

Authorities say police found scoped rifles, wigs, fake IDs and a bulletproof vest in the 28-year-old's rented truck after he was pulled over in the Denver area last weekend, ahead of the Democratic National Convention there. The resulting investigation led to the arrest of Gartrell and two other men who authorities say talked about killing Obama.

The U.S. Attorney's Office later said Gartrell and the other men were drug users making racists threats and had no firm assassination plot, and no capacity to carry out any attack.
