The man was detained next door to the president's home on Tuesday afternoon for having a gun. Investigators say the man had made some comments about having a spiritual connection to the former president and said he just wanted to talk to him.
A gun was found in the glove compartment of the man's vehicle, but he has a permit for it.
He was determined not to be a threat and has been cooperative with authorities even after he was released from their custody.
The Bushes were not home when the incident occurred.
