Left-wing protesters demonstrated outside the homes of Gantz and Knesset Speaker Yuli Edelstein on Friday afternoon.
The protesters complained that Knesset committees have not been set up yet. Edelstein has said they will be set up on Monday and Gantz's party went to the Supreme Court to ensure that they would be set up, but the protesters said they wanted to make a point about Netanyahu continuing to serve despite his indictments.
"A black flag is flying over the actions of the indicted prime minister," the protest organizers said. "But he is not the only one who is guilty. Our elected officials collaborating with his anti-democratic actions is a crime against Israeli democracy."
The protesters said they demonstrated outside Gantz's home in Rosh Ha'ayin "to remind him that he has a spine and balls." Dozens of cars came near Gantz's home.
They also protested outside the Tel Aviv home of Likud MK Gideon Sa'ar and the Kiryat Ono home of Public Security Minister Gilad Erdan "to remind them that they are not dish rags."
Edelstein blasted the protesters, saying that they were sent by the left-wing inside Blue and White to pressure Gantz not to join a national unity government.
Gantz spoke to his supporters Saturday afternoon after a group of them stood outside his door chanting as they expressed their faith in him, and his future actions.
"I will do everything the law, and the political reality allows me," Gantz reassured his supporters, after they begged him "not to fall into Netanyahu's trap."
But he also said "the coronavirus is top priority right now."
A pro-Netanyahu rally will be held on doorsteps and porches across the country at 6:00 pm on Sunday evening.
