Maryland State Senator Thomas Miller Jr. (D) resigned on Dec. 23 due to health reasons. He had announced in Jan. 2019 that he had been diagnosed with cancer.
Miller had represented District 27 since 1975. He served as Senate president for 33 years—from 1987 to 2020—the longest anyone has served as Maryland Senate president, according to The Washington Post. Prior to joining the state Senate, Miller served in the Maryland House of Delegates from 1971 to 1975.
According to Maryland law, the governor has 30 days after the vacancy to make an appointment based on the recommendations of the political party committee that holds the vacant seat. The political party committee has up to 30 days after the vacancy to submit a list of recommended candidates to the governor. If the party committee fails to act within the 30-day deadline, the governor has 15 days to appoint a person from the political party that last held the seat.
