This is the second time that the two ministers testify in Case 1000 (the "gifts affair") and in Case 2000 (the "Netanyahu-Moses affair")
Sources involved in the investigation said Netanyahu did not give elaborate answers.
"The prime minister did not give explanations, but rather empty slogans. He repeated several times that everything he did ‘was for the benefit of the State of Israel,'" the source said.
During the questioning, Netanyahu was confronted with the evidence provided by his former advisor turned state witness Nir Hefetz.
It is also reported that police sources said they reject the prime minister’s statement, released following the questioning, where he downplayed the investigation saying it lacks “meat” or “bone”.
"Now, after the 12th round of questioning, it has been made absolutely clear that not only is there is no meat in the prime minister's investigations, there isn't even a bone," it stressed.
"There is meat, and there are quite a few bones," the police sources vented.
On Friday morning, investigators from the Lahav 433 anti-fraud unit arrived at Netanyahu's official residence in Jerusalem as protesters gathered outside with a large banner bearing Netanyahu's face and the words "crime minister" and chanting slogans calling for justice.
The investigators are reported to have completed the questioning in Cases 1000 and 2000 and have already recommended to indict the prime minister for bribery.
