Statement on CAIR Pittsburgh Call for Resignation of Mr. Jack Cairns
Today, we were made aware of offensive, anti-Muslim, Facebook posts made by a member of our Robinson Township Republican Committee, Jack Cairns. The RCAC in no way endorses the comments or views of Mr. Cairns, and we condemn, in the strongest terms possible, these hateful posts.
The mission of the Republican Committee of Allegheny County is to foster the growth and prosperity of all residents of Allegheny County regardless of their race, religion, or creed.
Mr. Cairns has resigned, effective immediately, from his membership within the Robinson Township Republican Committee and the Republican Committee of Allegheny County.
