Washington (CNN) - The ink has barely dried on Rep. Jane Harman's letter to constituents notifying them she may resign from the House of Representatives, but one potential replacement has already announced her candidacy.
Los Angeles City Councilwoman Janice Hahn, a Democrat, announced this afternoon that she will run for the vacant seat.
Hahn wrote in a statement, "I'm running for Congress to create new jobs, expand clean energy technologies and ensure that local small business owners get the help and opportunities they need to flourish in a global economy."
Hahn, 58, currently represents portions of the Los Angeles area of South Bay on the city's council. She serves as chair of the council committee responsible for oversight of Los Angeles International Airport and the Port of Los Angeles.
In 2010 Hahn ran unsuccessfully for California's lieutenant governor, losing to former San Francisco mayor Gavin Newsom.
Democratic sources tell CNN that Harman, a Democrat, will leave the House to take a job with the Woodrow Wilson Center, a Washington, D.C. based think tank.
