Ashrawi was denied a travel visa to the United States earlier this month.

“It is official! My US visa application has been rejected. No reason given,” she wrote on Twitter. “Choose any of the following: I’m over 70 & a grandmother; I’ve been an activist for Palestine since the late 1960’s; I’ve always been an ardent supporter of nonviolent resistance.”

Ashrawi told the AFP that her daughter and grandchildren live in the United States, and that she travels to America three or four times a year. She said she has never before been denied a visa.

Ashrawi, a member of the PLO executive committee and former PA Minister of Higher Education and Research, has been a Palestinian spokesperson for the last 30 years.

Duss has an anti-Israel background as he, along with Sanders campaign manager Faiz Shakir, has been accused of furthering antisemitic conspiracy theories during his tenure at the left-wing think tank Center for American Progress.

He allegedly was part of CAP’s 2012 antisemitic incident where several staffers at the center’s ThinkProgress website, which Shakir served as editor-in-chief, were condemned for using antisemitic tropes of Jews dominating politics and money.

The staffers accused “pro-Israel Jews and members of Congress of being ‘Israel firsters,’ a term implying that those who support the Jewish state have dual loyalties,” according to the Free Beacon.

The row caused the firing and departure of several ThinkProgress writers.

At the time, Duss was CAP’s Middle East director, which has been known to be a stronghold for anti-Israel propaganda.

He also faced a backlash for publicizing Nazi-era propaganda posters in 2013.
