Authorities formally charged Vladimir Arutyunian with terrorism on Tuesday, Arutyunian's lawyer Guliko Dzhimsheladze told The Associated Press. Dzhimsheladze said her client admitted to illegally possessing weapons, but she did not mention his televised confessions to having thrown the grenade. The man wanted to murder Bush, she said.
"Arutyunian doesn't deny that he wanted to kill U.S. President George Bush. He explained the reason. My client believes that Bush is interfering in Georgia's internal affairs," she said.
"He maintains that this attempt on Bush's life should not be punished by law," she said of her client.
Arutyunian didn't want any Georgians to die in the attack, she said.
Both Mr. Bush and Georgian President Mikhail Saakashvili had been behind a bulletproof barrier addressing a rally of thousands in Tbilisi when the grenade landed about 100 feet away. It did not explode, and investigators later said it apparently had malfunctioned.
No one was harmed in the May grenade incident, but Arutyunian was charged earlier with killing a police officer in a shootout during his arrest, as well as illegal possession of weapons. He was shown on local television last week admitting throwing the grenade.
Georgian authorities, working with the FBI, were still trying to figure out Arutyunian's exact motives. Georgia's Interior Ministry said that Arutyunian was believed to have been a member of a political party that supports the former leader of a region largely outside central government control.
Aslan Abashidze, the former leader of the Adzharia region, fled to Russia last year amid street protests against his authoritarian rule. Mr. Bush had been visiting Georgia in an effort to cement relations between the United States and Georgia's new pro-Western leadership.
