Maryland's legislature normally meets in Annapolis for a 90-day session beginning each January, but lawmakers need a special session this year to redraw Congressional districts based on the results of the last census.
It's possible that lawmakers would consider additional legislation during the special session as well, AP reports.
Some members have discussed introducing bills to raise money for the state's depleted Transportation Trust Fund. But it's unclear how much support there would be to take on such challenging revenue issues.
A spokesman for the governor says O'Malley is still considering that possibility.
