Surprisingly however, when presenting her ministry's official stance, Justice Minister Ayelet Shaked asked Reuven Rivlin to take into consideration Olmert's "unique contribution to national security."
Shaked has stated that the decision lies solely at the hands of the president, and made it clear that she will support any decision he makes.
Olmert, who is serving a 27-month prison sentence for a corruption, submitted the pardon request late in January this year.
He is set be released from jail in the summer of 2018. However, if a third of his sentence is deducted, he will be discharged in October this year.
Last September, the Supreme Court rejected three appeals by Olmert and ordered that he serve eight months in prison in addition to the 18 months he was already serving for bribery in the Holyland real estate case.
Olmert was convicted for receiving and using over $150,000 in envelopes from US businessman Morris Talansky between 1993 and 2002.
The trial began in 2008, when Olmert was still the prime minister. Olmert appealed the ruling, but it was unanimously rejected.
