The Al-Maghrib Institute in Houston, an Islamic learning center, confirmed today that Umar Farouk Abdulmutallab attended classes there in August, 2008. Authorities earlier disclosed Abdulmutallab's visa showed he was in Houston from August 1, 2008 to August 16, 2008.

The international institute is a nonprofit that teaches Islamic studies. It has a student body totaling more than 20,000, Basyouni said, and conducts seminars in the U.S., Canada and the United Kingdom.

It's not a radical school and its Vice President says the subjects he lectures on include "reclaiming Islam from jihadists, focusing specifically on the issue of preventing terrorism."

Abdulmutallab supposedly wanted to study Sharia law. Houston has a Sharia Law Center, but this isn't it. The FBI has already visited the hotel he is believed to have stayed at, the Sheraton Houston Brookhollow Hotel.
