Fox News Channel personality Glenn Beck's rallies in Washington, D.C., are an attack on religious liberty and our nation's rich religious diversity, says Americans United for Separation of Church and State.

Tonight's event at the Kennedy Center, "Divine Destiny," is billed by Beck as a way to "reunite" Americans, "heal your soul" and take a "look at the role faith played in the founding of America and the role it will play again in its destiny."
