A Politico article from April 4th, "A blinking red light for Israel in American politics", opens with the observation that US leadership is "nearly" out of patience.
The Politico article went on to say something that would've been unimaginable just a few months ago:
A House Democrat who didn’t want to run afoul of the White House added that Biden is “feeling a ton of pressure from outside of his inner circle. Most of us are fed up, and I think the bottom is going to fall out on support for additional Israel security funding, at least in the Democratic caucus.”
Biden speaking to the Israeli PM, again asked Israel to dial it down a bit. However, this isn't the first such request. The killing of aid workers has been going on for months in full view of the media, approaching 200 killed, per the UN Secretary General.
If Netanyahu continues to blow off requests from Biden, the record of US Congressional support or opposition could take on more political significance - especially if the humanitarian crisis continues on the current trend.
Is there any organization (on either side of the issue) tracking where members of US Congress stand on this?
Alternatively, which Democratic members of Congress have taken a stand on the issue, in light of recent developments?
