Sen.-elect Kay Hagan received $199,000 from unions in 2008.
The Greensboro Democrat received donations from 29 political action committees affiliated with labor unions during her run for the Senate, according to federal campaign finance reports.
Top donors included the Teamsters, the National Education Association, the American Federation of Teachers, United Food and Commercial Workers, the International Association of Firefighters and the Communications Workers of America, which each gave $10,000.
She also received significant donations from the AFL-CIO, the American Federation of State, County and Municipal Employees and the United Transportation Union.
Change to Win, a federation of unions including the Teamsters, also made robocalls on Hagan's behalf, and the SEIU and the UFCW donated to Majority Action, which ran ads attacking Sen. Elizabeth Dole.
