Lincoln Chafee, the Republican-turned-independent who currently serves as the governor of Rhode Island, will address the Democratic National Convention on Tuesday night.
Chafee served a single full term in the Senate (as a Republican) before being unseated by now-Sen. Sheldon Whitehouse (D) in 2006. He won the governorship in Rhode Island as an independent in 2010, after leaving the GOP in 2007. During their time in the Senate together, Chafee and Obama formed a bond. WPRI of Providence:
Chafee and Obama formed a bond when they served in the Senate together for two years and have become political allies of a sort since Chafee left the GOP - he endorsed Obama for president in 2008, and Obama stayed neutral rather than endorse Chafee rival Frank Caprio in their hard-fought 2010 gubernatorial battle.
"We go way back," Chafee told WPRI.com in February, recalling when he and the future president used to work out together in the Senate gym.
