A man who threatened to kill President Barack Obama just before the 2008 Democratic National Convention in Denver has pleaded guilty to federal weapons charges.

Thirty-five-year-old Shawn Adolf faces 10 years in prison after pleading guilty to having firearms as a felon. Adolf was arrested in August of last year after officers in a Denver suburb pulled over his cousin and found rifles, a bulletproof vest, wigs and fake IDs.

That stop led agents to Adolf, who talked about plans to kill Obama with the rifle.

Authorities later determined the men were addled by drugs and had no specific plans to assassinate Obama. The cousin was already sentenced to 15 days in prison and six months in a halfway house for possession of methamphetamine.
