At 11 a.m. this morning, the Rev. Al Sharpton and former NY State Comptroller Carl MaCall will announce their support for Senate candidate Gustavo Rivera at a rally on the corner of Clinton Aveune and Oakland Place in Tremont.

Sharpton officially endorsed Rivera last week, but this is the first time he’s campaigned for him in the Bronx.

Former Senate candidate Desiree-Pilgrim Hunter (who dropped out of the race in July) is also expected at the event, which is being organized by the New Roosevelt Initiative, the group founded by businessman Bill Samuels. New Roosevelt is trying to convince voters to dump State Senator Pedro Espada, Jr. in next week’s Democratic primary, and has committed $250,000 to the cause.

We’ll be there this morning and will have an update later.
