Maryland Sen. Allan H. Kittleman, a former Senate Republican leader, plans to announce a 2014 bid for Howard County executive on Tuesday, according to a campaign advisory.

Kittleman, 54, will lay out plans for “a positive and inclusive campaign” focused on schools and other issues at an event attended by supporters from both major political parties, according to the advisory.

Kittleman, a Howard County native, also previously served on the Howard County Council.

While he has compiled a conservative record on fiscal issues in Annapolis, Kittleman supported two high-profile liberal social policies in recent years: the legalization of same-sex marriage and the repeal of the death penalty.

In 2011, he stepped down as Senate minority leader after announcing his support for a civil unions bill. He later voted for the legislation allowing marriage between gay couples.

Kittleman is seeking the office being vacated by Howard County Executive Ken Ulman (D). Earlier this week, Ulman joined the 2014 gubernatorial ticket headed by Lt. Gov Anthony G. Brown (D).
