Illuminating information from Rachel Ehrenfeld, who provides more information here:
The Department of Homeland Security had revoked Ramadan’s visa on July 28, 2004 under the Immigration and Nationality Act. The grandson of Muslim Brotherhood founder Hasan al-Banna was barred entry to the U.S. amid press speculation that the action involved a clause covering persons with a “position of prominence within any country to endorse or espouse terrorist activity,” or who have “potentially serious adverse foreign policy consequences for the United States.” Indeed, Ramadan who claims to be a moderate Muslim and a reformer, added his voice to Pope Benedict XVI’s critics for “inviting the peoples of the continent [Europe] to become aware of the central, inescapable Christian character of their identity, which they risk losing.” Ramadan sees the Pope’s message “deeply troubling and potentially dangerous in its reductionism.”
The U.S. gave no specifics for its 2004 revocation, but Ramadan’s activities, lectures and writings in support of the Islamist agenda were presumed the obvious cause. ……….
On December 8, 2005, the French prosecution of Chechen terror network chief Menad Benchellali revealed evidence of Ramadan’s links to terrorists in Europe. Benchellali had traveled to Switzerland “one or two times in 2000, to attend conferences on Islam provided by Tariq Ramadan.” Benchellali, who later planned chemical attacks in France “under the supervision of Abu Musab Al Zarqawi,” in June 2006 was sentenced to 10 years in prison.
Earlier, in March 2005, Algerian al Qaeda member Djamel Beghal received 10 years in prison in Paris for participating in a foiled terror attack on the U.S. embassy there. Beghal testified in September 2001, that “his religious engagement started in 1994” when “he was in charge of writing the statements of Tariq Ramadan.” That October, Beghal added that he had also taken “courses given by Tariq Ramadan.”
Moreover, a 2001 Swiss intelligence memo said: “brothers Hani and Tariq Ramadan coordinated a meeting held in 1991 in Geneva attended by [al Qaeda leader] Ayman Al Zawahiri and Omar Abdel Rahman,” the imprisoned planner of the 1993 World Trade Center attack.
Spanish judge Balatasar Garzon, meanwhile, reported Ramadan’s “routine contacts” with Algerian Ahmed Brahim, the alleged financial chief of Al Qaeda and financier of the 1998 U.S. embassy bombings in Kenya and Tanzania.
In 1995, when the Algerian Armed Islamist Movement, (AIM) perpetrated several terrorist attacks in Paris, French interior minister, Jean Louis Debre, barred Ramadan from France based on his links to AIM.”
