(CNN) – Connecticut Attorney General Richard Blumenthal will announce Wednesday that he'll run for Sen. Chris Dodd's seat, a highly placed Connecticut Democrat tells CNN.
Blumenthal is expected to announce his bid for Senate at a news conference at Connecticut Democratic Party headquarters in Hartford Wednesday afternoon.'
Dodd, a five term Democratic senator, plans to announce his retirement Wednesday, two sources close to the lawmaker told CNN. He plans to announce the decision at a news conference just two and half hours before Blumenthal's scheduled event. Dodd, 65, had been considered one of the most vulnerable Democrats seeking re-election in 2010.
The 63-year-old Blumenthal has been Connecticut's attorney general since 1990 and served in the state legislature from 1984 to 1990.
