Washington (CNN) - A second Democrat has officially jumped into the race to succeed Sen. Joe Lieberman of Connecticut.
Thursday Rep. Chris Murphy announced that he's a candidate.
"I'm running for the United States Senate. Connecticut deserves a new progressive voice in the Senate who listens to us," says Murphy in a video on a new Senate campaign website.
Murphy's announcement comes one day after the four term Democrat turned independent senator announced that he would not run for a fifth term in the Senate next year.
Murphy, who represents the state's fifth congressional district, located in the north-central and northwestern part of Connecticut, won re-election to a third term in November. He's expected to head to Connecticut later Thursday for an announcement event.
Tuesday former Connecticut Secretary of State Susan Bysiewicz formally announced her candidacy for Lieberman's seat. Rep. Joe Courtney is also considering a bid for the Senate.
On the Republican side, 2010 Senate nominee Linda McMahon, 2010 Senate candidate and former Rep. Rob Simmons, and 2010 GOP gubernatorial nominee Tom Foley are considered potential candidates.

Connecticut deserves a new progressive voice in the Senate
Maybe YOU think this, maybe CT thinks this (we'll see in 2012), but I can guarantee you the country does NOT think the answer is MORE progressives in Congress. The country has no desire to be another bankrupt Greece.
People of CT, please think long and hard before voting for a progressive. If you think the problems we have are because we have too little government control and spending then there is no hope for your state.
I trust the Democrats in CT won't make the same mistake as their lame bretheren in Massachusetts and allow a Tea-Party backed republican, like Brown to steal a seat.
I hope the Mass Dems are prepping a powerhouse candidate NOW to regain that seat.
I'm so happy to see Lieberman go. He hasn't represented my values in a very long time. I really like Chris Murphy, I hope he'll be a strong candidate.
Susan Bysiewicz should be hiding somewhere after she bungled the announcement of the governor's race before the vote count was done and after her office failed to notice there weren't enough ballots for people to vote in Bridgeport. She also tried to run for AG without meeting the requirements, I guess she thinks the rules don't apply to her.
There has to be a LOT of money to be made, in Washington. Too many people want the job, and frankly, nobody should!
I vote for Republikans, they are better alternative for US
