John Kerry would write them another permission letter, but his signature isn't worth much anymore.
The media left is fuming about Israel's ban on pro-terrorist BDS groups.
They include
American Muslims for Palestine - Established in 2005 by UC Berkeley lecturer Hatem Bazian, American Muslims for Palestine (AMP) is a major supporter of the pro-Hamas campus group, Students for Justice in Palestine (SJP). Several of AMP's current board members and key officials were previously members of, and worked closely with, now-defunct Islamic extremist groups that funded terrorist activities. These groups included the Islamic Association for Palestine (which, until its dissolution in 2004, served as the chief U.S. propaganda arm of Hamas)
Code Pink - Hamas protected the demonstrators during their two-day stay in Gaza by tightly controlling their movements and contacts, and by having them stay in a Hamas-owned, Five-Star hotel that one demonstrator characterized as "the nicest hotel I’ve ever stayed at.”
Next, the demonstrators prepared to go to Egypt, to participate in a Hamas-organized "Gaza Freedom March," again to protest Israeli policy. Code Pink co-founder Medea Benjamin told the media that Hamas “has pledged to ensure our safety” in Egypt. Joining Code Pink on the trip were former Weather Underground terrorists Bill Ayers and Bernardine Dohrn.
American Friends Service Committee - In the 1970s John McAuliffe, who then headed AFSC's Indochina program, initially characterized the news of Cambodian massacres under Pol Pot as an American "misinformation campaign," and lauded the Pol Pot regime as "the example of an alternative model of development and social organization." AFSC also distributed a printed defense of the Khmer Rouge well after the genocide in Cambodia had been exposed.
Jewish Voice for Peace - In October 2015, JVP issued a statement in support of Rasmea Odeh, mastermind of a February 1969 supermarket bombing in Jerusalem in which members of the Popular Front for the Liberation of Palestine had murdered two young Jewish men.
National Students for Justice in Palestine - A number of SJP chapters hold annual commemorations in honor of the late Hassan Al-Banna, founder of the Muslim Brotherhood, which Islam expert Robert Spencer has described as “the parent organization of Hamas and al Qaeda.” Al-Banna was an inveterate Jew-hater who firmly opposed the creation of Israel in 1948 and strove to forge a formal alliance with Hitler and Mussolini when World War II broke out.
