A number of LGBT advocacy groups and several local elected officials will be demonstrating tomorrow afternoon on the steps of the Bronx County Courthouse in support of marriage equality.

The rally was organized by Bronx Rainbow Independent Democratic Association and Marriage Equality New York.

Expected to attend: State Senators Jose M. Serrano, Gustavo Rivera, Jeff Klein and Adriano Espaillat, Assemblymembers Carmen Arroyo, Jeffrey Dinowitz and Jose Rivera and NYC Councilmember Maria del Carmen Arroyo.

According to a press release, the event is in part a response to State Sen. Ruben Diaz, Sr.’s controversial March 15 parade against the passage of a gay marriage bill for New York.
