What statements did they make in support of Hamas or their actions? Forgive me for not taking that claim at face value given that literally any pro-Palestinian speech, no matter how measured, tends to get conflated with support for terrorism and/or anti-semitism. Even something as benign as wearing a keffiyeh in solidarity, which the ADLs CEO likened to wearing a swastika.
The closest to it is that the organization he represented supported resistance "by any means, including armed resistance" immediately after 7.10.23. But AFAIU they were very careful not to mention Hamas, positively or negatively.
