"As a 30-year veteran of the US House of Representatives who served in Democratic Party leadership as Caucus Whip for a decade, I recognize the experience and leadership approach necessary for faithful and effective civil servanthood. And I see those traits in Pastor Chris Butler, congressional candidate for the 1st District of Illinois. His track record of putting the people of his community first, lifting their voices even when their backgrounds and perspectives differ from his, and standing strong against unhelpful political power-plays demonstrates that he will truly uplift the 1st District and the nation overall as Congressman. I know that Chris is ready to serve in Congress. His leadership will move us forward."

Former Congressman David Bonior served as Democratic whip in the House from 1991 to 2002, during which time Democrats were in both the majority (1991–1995) and minority (1995–2002), making Bonior the third and second highest-ranking Democrat in the House, respectively. Following his retirement from the House, Bonior became a professor of labor studies at Wayne State University and founded American Rights at Work, a union advocacy organization of which he currently serves as chairman. After the election of Barack Obama in November 2008, Bonior served as a member of the president-elect's economic advisory board.
