Warren to be keynote speaker at MLK commemorative service on the day before inauguration.

Rev. Rick Warren, who is President-elect’s controversial pick to give the invocation at his inauguration on Jan. 20, will be the keynote speaker at Martin Luther King, Jr. Annual Commemorative Service at the historic Ebenezer Baptist Church on the day before the Inauguration, Atlantic Progressive News reports. Before she passed away, King’s wife, Coretta Scott King, declared that gay marriage was a civil rights issue and denounced a proposed constitutional amendment that would ban it.
