On Wednesday, journalist and commentator Wajahat Ali announced on social media that the Islamic Society of North America, or ISNA, had disinvited him from speaking at their upcoming annual convention in Houston on Labor Day Weekend for his recent work with Israel.

In a letter, Altaf Husain, vice president of ISNA, writes that the organizers reached a decision not to include Ali as a speaker for his “recent work,” specifically citing that “other than our creed as Muslims, there is perhaps nothing more exemplary and unifying than our community’s support for the Palestinian people of all faith traditions, in their struggle against occupation and dispossession.”
