Representative John Yarmuth, a Democrat representing Kentucky, boycotted the 3 March 2015 Netanyahu speech (more like pep rally) before Congress. He was criticized by the right-wing media, which tried to claim that the exceedingly pro-Israel Democrats who chose not to attend the speech did so out of some kind of supposed liberal hatred of Israel, rather than mere partisan obedience to the Obama administration.
In an interview, Yarmuth firmly insisted “I am a strong supporter of Israel, but my first obligation is to the Constitution of the United States, not the Constitution of Israel.”
The congressman’s blind devotion to an apartheid state aside, those even vaguely familiar with the politics of Israel will know that Israel does not have a constitution. That is a basic fact.
On its official website, the Israeli Knesset (parliament) writes:
Israel does not have a written constitution, even though according to the Proclamation of Independence a constituent assembly should have prepared a constitution by October 1, 1948. The delay in the preparation of a constitution resulted primarily from problems that emerged against the background of the alleged clash between a secular constitution and the Halacha (the Jewish religious law).
Throughout its almost 70 years of existence, Israel has never adopted a written constitution.
Virtually all American politicians are die-hard Zionists—especially the far-right evangelical Christians (who are also anti-Semites, but this is by no means the first time in history Zionism allied itself with anti-Semites)—but virtually none of them know even the most basic facts about the settler colonialist apartheid state of Israel.
