(AllHipHop News) Def Jam co-founder/Hip-Hop mogul Russell Simmons has thrown in his support for a controversial mosque being built near the site of the 9/11 terror attack in Manhattan in 2001. Simmons has placed a series of religious symbols on the panes of his Liberty St. penthouse, which spells out the word "Co-Exist."Other messages in the windows of Simmons' home include "It's the Law" and "USA is Free."The $100 million mosque, which is just two blocks away from ground zero, has been a lighting rod for controversy. "This is compelling for Russell because he lives here and he's always involved with issues of people getting along," Simmons' associate Glen Friedman told the New York Post. Simmons' Liberty St. pad was one of several building destroyed and rebuilt after the 9-11 disaster. "If your blaming Muslims for the attack on 9/11 then you need to change your mind," Simmons said about the controversy surrounding the mosque. Did we blame Christians for the first world trade attack? It creates a cycle of negativity."Manhattan's community board voted 29-1 in favor of the mosque, which is being built by the Cordoba Intiative.
