The man who wounded US president Ronald Reagan in 1981 has apologised for his actions and says he does not remember what he was feeling when he fired the shots that also wounded three others.
John Hinckley Jr told CBS Mornings in his first televised interview since he was freed from all court oversight this month that he feels sorry for all the lives his actions affected.
"I feel badly for all of them. I have true remorse for what I did," Hinckley said.
"I know that they probably can't forgive me now but I just want them to know that I am sorry for what I did."
Asked about what feelings led him to commit the act, Hinckley said he cannot remember those emotions and does not want to.
"It's such another lifetime ago. I can't tell you now the emotion I had right as (Reagan) came walking out. I can't tell you that," he said, later adding: "It's something I don't want to remember."
Hinckley was 25 and suffering from acute psychosis when his gunshots wounded Reagan and three others outside a Washington DC hotel.
The assassination attempt paralysed Reagan press secretary James Brady, who died in 2014.
It also wounded a police officer and a Secret Service agent.
Jurors found Hinckley not guilty by reason of insanity and he spent decades at a mental hospital in Washington DC.
He began making visits to his parents' home in Williamsburg, Virginia, in the early 2000s.
A 2016 court order granted him permission to live with his mother full time, albeit under various restrictions, after experts said his mental illness had been in remission for decades.
He signed a lease on a one-bedroom apartment in the area last year and has been living alone there with his cat, according to court documents.
His mother died in July.
He has also been releasing songs and looking for a venue willing to let him sing and play guitar before a live audience.
He has posted videos of himself singing and playing a guitar on YouTube.
Hinckley had previously been under restrictions that barred him from owning a gun, using drugs or alcohol or contacting members of the victims' families.
But a federal judge in Washington DC had said months ago that he would free Hinckley from those restrictions if he remained mentally stable.
Those restrictions were lifted on June 15.
