Toppled..

Longtime labor leader George Gresham was toppled by his former lieutenants in a contentious race to lead the nation’s largest health care union.

Gresham, who became president of 1199SEIU United Healthcare Workers East in 2007, lost his reelection bid by a resounding margin to challenger Yvonne Armstrong, who leads the union’s long-term care division, according to data reviewed by POLITICO.

The union is conducting an independent review of Gresham’s spending, after a nine-month POLITICO investigation revealed that he had long used members’ dues money to benefit himself, his family and political allies. 

The House Committee on Education and the Workforce subsequently asked the U.S. Department of Labor to investigate.
