Flanked by several legislators, Jealous said he intends to return to Annapolis repeatedly through the 90-day legislative session that starts Wednesday to work for repeal.
Death penalty opponents have come close in recent years to securing the votes needed to remove capital punishment from the books, but each time have fallen a few votes short.
This year, they are hoping that lingering doubts about the guilt or innocence of Troy Davis, a 42-year-old who was convicted of murder in 1981 and executed in Georgia in September, will give fresh impetus to their efforts.
Jealous, who noted that he will soon move to a new House in Silver Spring, said he plans to meet with Gov. Martin O'Malley soon to urge him to step up efforts to secure the votes needed for repeal.
