WASHINGTON--Sen. Dick Durbin (D-Ill.) hit two fund-raisers on Sunday, stockpiling cash for his 2014 re-election bid with events at the homes of two of his major supporters, Susan and Lew Manilow in Chicago and Dan and Fay Levin in Winnetka.

The events at the Manilow and Levin homes were attended by Durbin's circle of longtime donors.

Susan Manilow, a long-time Democratic activist, is the finance chair of Durbin's campaign. Lew Manilow, a real estate developer, is also a long-time Democratic activist who, in 1992, was President Bill Clinton's national vice-chair and Illinois Finance Chair.

Dan Levin is the founder and chairman of The Habitat Company. Fay Levin is the former United States Ambassador to the Netherlands, tapped by President Barack Obama. She served between 2009 and 2011.

Durbin's fundraising has been and continues to be handled by the Chicago-based Nancy Kohn.
