Democrat State Senator Katherine Clark began her campaign for a seat in the US House of Representatives Friday.
Clark, a Melrose resident who represents Malden, Melrose, Reading, Stoneham, Wakefield, and Winchester, launched a website for the campaign and began seeking donations.
A statement posted on KatherineClarkforCongress.com touted Clark's track record in the state level.
"The climate in Washington is divisive right now, but that is exactly why I want to represent our values in Congress," the statement said. "I have a proven track record of bringing people together to find common sense solutions that create opportunity and move us forward."
Clark served as a state representative for Melrose and Wakefield from 2008 to 2011, when she was elected to succeed Richard Tisei in the state Senate. She was reelected last year.
A former prosecutor in Colorado before moving to Massachusetts, Clark has recently been vocal on reforming the state's Sex Offender Registry Board and called to make more sex offender information available to the public. She currently serves as chairwomen on the Joint Judiciary Committee, and chairwoman of the Senate Committee on Steering and Policy.
In Melrose, she served on the school committee from 2001 to 2007.
Clark joins a building list of Democrats seeking Ed Markey's seat representing the 5th District. The seat will only come free if Markey wins a special election for John Kerry's seat in the US Senate in June.
State Representative Carl Sciortino of Medford and state Senator William Brownsberger of Belmont have declared their candidacies. Other Democrats who have been mentioned as possible candidates include State Senator Karen Spilka of Ashland, Peter Koutoujian, the Middlesex sheriff, and state Representative David Linsky of Natick.
