Baltimore City Council President Bernard C. “Jack” Young (D) is among the elected officials lined up to endorse the gubernatorial bid of Lt. Gov. Anthony G. Brown (D) on Saturday, according to several people familiar with the plan.

Brown’s campaign announced Friday that it would roll out new endorsements in both Baltimore and Montgomery County on Saturday.

Young is among five elected officials who plan to endorse Brown at an event in Baltimore, which is planned at a new campaign office that Brown is opening in the city, according to a Brown aide. Brown expects to collect 16 endorsements from elected officials in Montgomery, the aide said.

Young has served as city council president since February 2010, when he was chosen to fill the remainder of the term of now-Mayor Stephanie Rawlings-Blake (D), who has also endorsed Brown. Young was elected citywide to the position of council president in 2011.

The people who confirmed Young’s plans to endorse Brown requested anonymity Friday because they were not authorized to speak for Young or the Brown campaign.

In the early stages of the governor’s race, Brown has dominated the endorsement process.

Brown faces Attorney General Douglas F. Gansler and Del. Heather R. Mizeur (Montgomery) in the June Democratic primary.
