Senator Joe Lieberman (I-Conn.) will not seek another term in 2012, according to reports from various media outlets.
Lieberman, who has served in the Senate since 1989, will reportedly make the announcement Wednesday from Stamford, Connecticut, his hometown.
The centrist Senator’s last race was his closely-watched 2006 campaign, wherein he lost the Democratic primary to Ned Lamont, but ultimately won his state running as an independent.
Following his win, Lieberman became an important swing vote and often straddled the middle, noticably leaning to the right with his endorsement of Republican John McCain in 2008’s Presidential race and bowing toward the left by spearheading the repeal of Don’t Ask, Don’t Tell.
News of Lieberman’s retirement follows announcements from Senators Kay Bailey Hutchinson (R-Texas) and Kent Conrad (D-ND).
Lieberman chairs the Senate Homeland Security Committee and was on the Democratic ticket as Vice President in 2000.
