Washington (CNN) - Democratic California Rep. Jane Harman is expected to announce her intention to resign from office on Tuesday and when she does she will face more questions about the timing of her decision.
Harman won her 9th term in office in November and was sworn in just last month. She is expected to announce she will leave Congress to head the Woodrow Wilson Center, a top think tank in Washington.
According to state election laws, the California governor is required to set the date for a special election, no later than 14 days after the seat is vacated.
California currently has a budget gap of $25 billion, and Los Angeles County, parts of which Harman represents, is facing a budget deficit of $3.5 million to $4.5 million.
On Monday, Harman's office offered no comment to questions about her departure date or whether she is concerned about the cost burden of a special election on her constituents.
According to the California Secretary of State's office, individual counties foot the bill for special elections.
The Los Angeles County Registrar's office estimates that the special election to fill the seat vacated by Hilda Solis in 2009 cost $1.5 million. Solis left her seat in Congress representing California's 32nd district to become secretary of labor under President Obama.
In a letter to her constituents, Harman said the decision has been "excruciating" because "the distinction of representing the smartest constituents on earth will never be surpassed."
"You have elected me to nine terms in Congress – an honor without equal," Harman wrote. "I hope you understand how truly grateful I am for your friendship and support."
