A man armed with a gun who tried to shoot Argentina's Vice President Cristina Kirchner has been charged with attempted homicide.
Fernando Sabag Montiel, 35, was caught on video pointing a pistol at Ms Fernandez de Kirchner from close range as she greeted supporters outside her home earlier this month.
The weapon failed to go off, for reasons still unknown, and Mr Montiel was overpowered on the spot and arrested.
His girlfriend, 23-year-old Brenda Uliarte, who was arrested three days after the incident, has also been charged.
Judge Maria Capuchetti, who is leading the case, issued charges of attempted aggravated homicide with premeditation against Mr Montiel and Ms Uliarte, who will remain in police custody, according to court documents.
The investigation has been based primarily on analysis of the suspects' social media accounts, computers and phones.
The accounts appear to have paid particular attention to the fact that Ms de Kirchner's supporters gathered near her house every night.
This "was studied in detail by the two (defendants) to choose the right time for the attack," Judge Capuchetti said.
Although the pair have not been shown to be politically radical, Mr Montiel did have tattoos of neo-Nazi symbols while Ms Uliarte showed clear hostility towards Ms Fernandez de Kirchner online.
In one message she said: "I sent (someone) to kill Cristina."

Judge Capuchetti has yet to issue charges against two of the couple's suspected acquaintances, 21-year-old Agustina Diaz, and 27-year-old Gabriel Carrizo, who were both arrested earlier this week.
Authorities had said earlier that there was evidence of "planning and prior agreement" between Mr Montiel and Ms Uliarte, though their motives have not yet been clearly established.
Ms Fernandez de Kirchner, the 69-year-old former president, enjoys a loyal support base among followers of the centre-left Peronist movement.
But she is disliked in equal measure by the political opposition, and is at the centre of a heated corruption trial from her time in office.
Argentina's highly polarised politics have been at the centre of debate since the attack, with politicians from both sides blaming each other for fomenting a "climate of hate".
The day after the attack, tens of thousands of people demonstrated in several Argentine cities to show her support.
She spoke publicly for the first time since the attempt on her life, during a meeting in the Argentine Senate with priests and nuns working in the slums around the capital.
"I feel that I am alive thanks to God and the Virgin Mary", she said.
She also said that Pope Francis had called her after the attack to express his support.
