They don't care really about Israel I think, what leverage would they have to pressure the US admin to do anything? I think this is about being critical of the people in government in general. If everyone is at risk of being deported, who would go and protest anything? That would certainly make me think twice about it.
I don't understand how you can ask that question with a straight face given the last 50 odd years.
Israel has enormous leverage over the US administration, through the AIPAC, a money laundering operation disguised as political lobbying, ensuring a steady flow of money from the US treasury to Israel govt. and right back to the Congress.

From AIPAC themselves: (https://www.aipacpac.org/)
> Being pro-Israel is good policy and good politics.
> %98 of AIPAC-backed candidates won their general elections.
> $70M contributed through AIPAC to support pro-Israel candidates.
> We helped defeat 24 candidates who would have undermined the US-Israel relationship.
Democracy anybody?
Now imagine Russia had a similar organization, what would the reaction be? Yet when it's Israel, it's somehow fine.
From Wikipedia: (https://en.wikipedia.org/wiki/AIPAC)
> AIPAC was founded in 1954 by Isaiah L. Kenen, a lobbyist for the Israeli government, partly to counter negative international reactions to Israel's Qibya massacre of Palestinian villagers that year.
They have been very open and vocal about their reason. And it's not just the republicans. The democrats also support it as well. Pretty much the only thing the republicans and democrats both agree on.
