Macklemore Joins Americans United

LGBT ally and rapper Macklemore, whose singles have topped the Hot 100 for months, is speaking out on behalf of Americans United for Separation of Church and State.

RELATED: Macklemore & Ryan Lewis' Can't Hold Us is #1 for the fourth consecutive week on Billboard's latest pop singles chart. Their previous single, Thrift Shop, held the top spot for six weeks and has been RIAA-certified as quintuple platinum. The act shot to global prominence last year on the strength of Same Love, their hit single that pays tribute to same-sex relationships.
