Gubernatorial candidate Susan Bysiewicz is dropping her bid in order to become Ned Lamont's running mate, a source close to Lamont told NBC Connecticut political reporter Max Reiss Monday.
On Tuesday, Lamont and Bysiewicz held a news conference and made the partnership official.
Democrats are preparing to hold their state convention this weekend.
Lamont has secured endorsements from some big names, including Attorney General George Jepsen, New Haven Mayor Toni Harp, and former Consumer Protection Commissioner Jonathan Harris, who dropped his own bid for governor to support Lamont.
Lamont is making his third attempt at statewide office, and second attempt at governor. He failed in his bid to win the Democratic nomination in 2010 to now-Governor Dannel Malloy.
