Happy 109th Founders Day to the women of Delta Sigma Theta Sorority, Inc.! Members of Delta Sigma Theta have a rich history in the Congressional Black Caucus, as the Honorable Shirley Chisholm is an original and founding member. As #CBC Chairwoman Rep. Joyce Beatty continues the legacy, we salute Delta Sigma Theta for their 109 years of service! #DST1913 #DST109 #J13 #congressionalblackcaucus #cbcpacconnects #cbcpac #ourpowerourmessage
