Then he ruined it by apologizing. A typical spineless OP reaction.
People won’t remember the apology. What is important is somebody spoke out during the speech.
I have to laugh, in Israel, where I’ve lived, Knesset members routinely shout at whoever is speaking at the podium, including the prime minister.
This was a big reason why Binyamin Netanyahu gave his policy speech in July at Bar Ilan University and not in the Knesset. He did not want his speech to be subject to outbursts from the Leftist and Arab legislators.
