I found a single video in which Biden is clearly not calling all protests antisemitic... Is this what you're referring to?

Of course they did 🤦

He's trying to legislate, goddammit. All it takes is typing "Bernie Sanders legislation" in a search engine, and use your goddamn eyes. Here's what he's trying to do:

My first amendment would ensure that we are not providing any more offensive military aid to Netanyahu’s war machine while he continues to violate U.S. and international law. This amendment would not touch funding for the Iron Dome or other purely defensive systems, but it would end aid to a war machine which has already killed 34,000 Palestinians and wounded 77,000, 70 percent of whom are women and children. And, right now, as we speak, hundreds of thousands of children face starvation as a result of that war machine.

The second amendment that I am offering would remove the prohibition on funding for UNRWA, the backbone of the humanitarian relief operation in Gaza and the only organization that experts say has the capability to provide the humanitarian aid that is desperately needed. Israel has alleged that 12 UNRWA employees out of 30,000 were involved in the Hamas terrorist attack on October 7. [...] That is being investigated and it should be. But you don’t allow thousands of children to starve because of the alleged violations and actions of 12 people.

Maybe try actually reading before replying.

He HAS been trying to legislate, but the AIPAC toadies in congress vote him down every time, spurred on by the AIPAC toady in the Oval Office.

You're basically blaming him for others stopping him from doing his job.

As for revealing who supports genocide, at last vote it was everyone in the Senate except him and 3 others and everyone in the House except the Squad and about a dozen others IIRC.

A simple search on multiple search engines about Bernie's history trying to legislate in the face of AIPAC would prove you're wrong.
