- Sen. Bernie Sanders says President Joe Biden needs to be tougher on Israel amid the war in Gaza.
- Sanders admonished Israel's Benjamin Netanyahu, who recently promised "nobody will stop us."
- 100 days into war, Israel's retaliation has killed nearly 24,000 Palestinians, 10,000 of them kids.
Sen. Bernie Sanders wants President Joe Biden to speak louder in support of Palestinians in Gaza — or risk his reelection.
