Masjid Omar ibn al-Khattab opened in 1994 and is situated adjacent to the campus of the University of Southern California (USC).  The mosque is a part of the Omar Ibn Al Khattab Foundation.[1]  The Omar Foundation has sponsored and hosted Muslim–Jewish dialogues and is represented on the Los Angeles Unified School District’s Human Relations Council and the Advisory Board of Days of Dialogue.[2]
A sizable amount of funding for the mosques construction came from the Kingdom of Saudi Arabia.[3]
The Omar Ibn Al-Khattab Foundation is a board member of The Muslim American Homeland Security Congress (MAHSC), alongside multiple Muslim Brotherhood-affiliated organizations.[4]
