From Huffington Post:
The Army has revoked the deployment orders for a soldier who said he shouldn’t have to go to Afghanistan because (he believes) Barack Obama was never eligible to be president.
Because he’s a reserve soldier who volunteered for an active duty tour he can “ask for a revocation of orders up until the day he is scheduled to report for active duty,” a public affairs officer explained. Cook volunteered for the tour in May of this year. It is not clear why he did so, considering his current objections.
