Ruppersberger's career in public service started decades ago as a seasonal police officer and lifeguard in Ocean City, and continued into the courtroom as a prosecutor. Later he entered politics as a council member and county executive in Baltimore County and eventually went to Congress for eleven terms.
Ruppersberger's retirement had been speculated and rumored for some time. He jokingly acknowledged it himself when his colleague U.S. Rep. John Sarbanes announced his own political retirement.
